Stresses and its components - Theory of Elasticity and Plasticity

Stress at any section is internal resistance offered by metal against the deformation caused by applied load.
It is Internal resistance pre-unit area.
When a metal is subjected to a load, it is deformed, no matter how strong the metal.
If the load is small, the distortion will probably disappear when the load is removed.
If the distortion disappears and the metal returns to its original dimensions upon removal of the load, the strain is called elastic strain.
If the distortion disappears and the metal remains distorted, the strain type is called plastic strain

Thin and thick cylinders

1. Cylinders are commonly used in engineering to transport or store fluids and are subjected to internal fluid pressures. This induces three stresses on the cylinder wall - circumferential, longitudinal, and radial.
2. For thin cylinders where the wall thickness is less than 1/20 the diameter, the radial stress can be neglected. Equations are derived to calculate the circumferential and longitudinal stresses based on the internal pressure, diameter, and wall thickness.
3. Sample problems are worked out applying the equations to example thin-walled cylinders under internal pressure, finding stresses, strains, and changes in dimensions.

3. The document presents sample problems and exercises for analyzing trusses using both methods and determining member forces and reactions.

Truss

The document defines a truss as a rigid structure composed of two force members connected at joints. There are three types of trusses: perfect trusses which have just enough members to remain stable under loading, deficient trusses with too few members, and redundant trusses with excess members. The key assumptions in truss analysis are that members are pin jointed and carry only axial forces, and trusses are loaded at joints. Two common methods to analyze trusses are the method of joints, which determines member forces by analyzing joints individually, and the method of sections, which analyzes equilibrium across a cut through selected members. Several example problems demonstrate applying these analysis methods to various truss configurations.

Trusses The Method Of Sections

The document discusses different types of structures and methods for analyzing trusses. Trusses are structures made of straight members connected at joints. Two common methods for analyzing trusses are the method of joints and method of sections. The method of joints involves drawing force diagrams at each joint and applying equilibrium equations. The method of sections involves cutting a truss and analyzing one side of the cut section. Zero-force members, which carry no load, can be identified and removed to simplify analysis.

Truss

1) A truss is a structure composed of straight members connected at joints that allows the members to only experience axial forces from the connections and any applied loads.
2) Trusses are divided into bridge trusses and roof trusses with various types of each including Pratt, Howe, Warren, and more.
3) Trusses can be analyzed through the method of joints which involves applying equilibrium conditions to each joint sequentially or the method of sections which uses equilibrium on a cut portion of the truss to directly find member forces.

Advanced control scheme of doubly fed induction generator for wind turbine us...

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

- 7. TRUSSSE Page 7 Method of Section: 1) When the forces in a few members of a truss are to be determined, then the Method of Section is mostly used. 2) In this method, a section line is passed through the members, in which forces are to be determined. 3) The section line should be drawn in such a way that, it does not cut more than three members in which forces are unknown. If force in the members CD, GD and GF i.e. FCD, FGD, and FGF respectively we want to calculate. Then pass a section line through these members. 4) The part of the truss, on any one side of the section line, is treated as a free body in equilibrium under the action of external forces on that part and forces in the members cut by the section line. See Fig. (1) and (2). 5) The unknown forces in the members are then calculated by using the equations of equilibrium. ∑M = 0, ∑Fy = 0 ∑FX = 0 Concept of virtual work: 1) Consider a force (P) is acting on a body which get displaces through a distance (s) due to applied force. Then, Work done = Force X Displacement W = F.s 2) But if the body is in equilibrium, under the action of a system of forces, then the work done is zero.
- 8. TRUSSSE Page 8 3) If we assume that the body, which is in equilibrium, undergoes a small imaginary displacement (virtual displacement) some work will be imagined to be done. Such imaginary work is called as virtual work. This concept is useful to find out the unknown forces in the structures. Principle of virtual work: “ If system of forces acting on a body (or a system of bodies) be in equilibrium and the system to be imagined to undergo a small displacement consistent with the geometrical conditions, then the algebraic sum of the virtual works done by all the system is zero”. i.e. mathematically, ∑W = 0 Types of virtual work: 1) Linear virtual work: If a force (F) causes a displacement (virtual displacement) in its direction of line of action, then its virtual work is given as, WV = F x δ Sign convention: Upward forces are considered as positive, while downward forces are considered as negative
