The document discusses the Erichsen cupping test for evaluating the formability of sheet metals. It defines formability as the ability of a sheet to be formed into a specific shape. Formability depends on parameters like strain hardening coefficient, strain rate sensitivity index, and plastic strain ratio. The Erichsen cupping test involves drawing a hemispherical dome in a sheet metal and visually inspecting it for defects like radial or circumferential cracks that provide information about the material's grain size, anisotropy, and ductility in different directions. Results are compared to standard charts to evaluate formability.

Small segmental portion of circumference of cylindrical sections was considered as width of composite laminate and of metallic plates, necessary to accommodate 5 rows of fasteners in transverse direction with specified pitch distance. Bolted radial joints between carbon epoxy helical wound flat laminate and 15CDV6 steel plates were realized with 8 numbers of steel fasteners distributed in 3 longitudinal and 5 transverse rows at each joint. Helical angle of winding, length and thickness of carbon epoxy laminate was Ā±22.5Ā°, 458mm and 11mm respectively. Length and structural thickness of radial joints, total length and width of assembly test specimen were 98mm, 18mm, 870mm and 169.43mm respectively. Joints were tested under uni-axial tensile load up to failure. Joints failed at 18 tonnes (1.7 times of design load). Failure mode was observed as initiation of bearing failure at all 8, countersink fastener holes in laminate and shear out failure at edge hole. Strains in fibre direction, at 45Ā°and at transverse to fibre direction were found very less. Maximum compressive strain and residual strain, near fastener holes were found as -1423 and -136 micro strain respectively. Test was successful.
Proof of ss 430 paper revised
The document analyzes the formability, fracture behavior, void coalescence, and texture of batch annealed (BA), continuous annealed (CA), and cold rolled (CR) 430 grade stainless steel sheets through tensile testing, forming limit diagrams, fractography, and texture analysis. Microstructural observations found elongated grains in the rolling direction, with average grain size decreasing in the order of CA, BA, and CR sheets. CA and BA sheets exhibited better formability than CR sheets based on forming limit diagrams and texture analysis, though CR sheets still showed satisfactory performance for certain applications.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to todayās integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.Ā

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.
