In this project we studied dynamic loading behaviour of different models of portal frame which are subjected to moving mass on top of horizontal beam. A finite element simulation has been carried out in order to study the behaviour of a transverse open crack in the horizontal segment of a portal frame while it is subjected to a moving mass. This portal frame is hinged to the ground and only in-plane vibrations are considered. The horizontal section is modelled as two segments connected by a rotational mass-less linear elastic spring. Portal frames are modelled using the C-coding. The characteristic equation is obtained with due consideration towards boundary and compatibility conditions. The resulting characteristic equation is a function of the frames natural frequency, crack location and crack depth. The frequency values are used to decide the appropriate time step for the dynamic analysis. The finite element modelling has been done with singular quadratic quadrilateral planar elements. Results are mainly used to calculate crack opening, crack closing and crack growth rate time. Various conclusive inferences have been made from the results obtained. The output solutions such as stress, strain and displacement was studied and discussed.

Coupled thermal fluid analysis with flowpath-cavity interaction in a gas turb...Nathan Fitzpatrick
This thesis discusses coupled thermal-fluid analysis of a gas turbine engine drive cone cavity. Five computational fluid dynamics (CFD) models of increasing complexity are analyzed: 2D axisymmetric, 2D with porous media bolts, 3D axisymmetric, 3D merged with upstream components, and 3D merged without bolts. Temperature, pressure, velocity and other flow parameters are compared across the models. Additionally, a finite element thermal model is coupled to the 3D CFD to determine metal temperatures in the cavity. The results provide insight into cavity flow physics and validation of the coupled thermal-fluid analysis approach.

They allow engineers to visualize and understand complex objects, structures, machines and their components. Drawings use standardized conventions, symbols and techniques to represent views, dimensions, materials, scales and other technical information precisely. They serve as roadmaps for manufacturing complex products. Manual drafting skills are still important for learning fundamental principles, even as computer-aided design has streamlined the process.

In structural design, torsional moment may, on occasion, be a significant force for which
provision must be made. The most efficient shape for carrying a torque is a hollow circular shaft;
extensive treatment of torsion and torsion combined with bending and axial force is to be found
in most texts on mechanics of materials.
When a simple circular solid shaft is twisted, the shearing stress at any point on a transverse
cross-section varies directly as the distance from the center of the shaft. Thus, during twisting,
the cross-section which is initially planar remains a plane and rotates only about the axis of the
shaft.
Torsion members are frequently encountered in structures and machines. A structural member
may need to resist torques induced by a load, such as wind or gravity. Machinery examples
include motor vehicle drive shafts, torsion bar suspensions, ship propeller shafts, and centrifugal
pump shafts. In the analysis of torsionally loaded members, we are primarily concerned with the
torsion stress and the angle of twist on the shaft. In our laboratory experiment, the primary
emphasis is on the recognition of torsion on the usual structural members, how the torsion
stresses may be approximated and how such members may be selected to resist torsion effects.
1) The report discusses using statistical process control tools to improve the process capability of a transmission shaft manufacturing process that was experiencing high rejection rates due to snap rings not fitting during assembly.
2) Analysis found the major cause of rejection was variation in the groove turning process that produced groove heights outside of the snap ring size range.
3) The report proposes expanding the available snap ring sizes or tightening raw material tolerances to reduce rejection rates and improve process capability. Implementing these changes through an experiment achieved a process capability over 1.6.
