Finite Element Simulation of Shot Peening and Stress Peen Forming
Shot peening is widely used to improve fatigue life of the metal component. It can also induce the distortion of thin component, which is called peen forming and is widely used for shaping aircraft wing skin. Shot peening surface coverage, intensity and saturation are important shot peening control parameters and have greatly influence on shot peening and peen forming results. Due to the insuff...
متن کاملThe optimisation of shot peen forming processes
An optimisation method based on an effective process model is presented. The calibrated and verified process model simulates peening on realistic components and provides a non-linear relationship between peening parameters and deflections. An optimal solution can be found by minimising the deviation of the computed deformed shape from the desired shape subject to certain constraints. This optim...
متن کاملStudy on Damage Tolerance Behavior of Integrally Stiffened Panel and Conventional Stiffened Panel
The damage tolerance behavior of integrally and conventional stiffened panel is investigated based on the fracture mechanics and finite element analysis. The load bearing capability and crack growth characteristic of both types of the stiffened panels having same configuration subjected to distributed tensile load is examined in this paper. A fourteen-stringer stiffened panel is analyzed for a ...
متن کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
Numerical Analysis of Severe Plastic Deformation by High Pressure Torsion
High-pressure torsion (HPT) is a metal processing method in which the sample is subjected to a very high plastic shear deformation. This process can produce exceptional levels of grain refinement, and provides a corresponding improvement in mechanical properties. To investigate the stress and strain distribution due to HPT process finite element simulation were conducted to investigate effectiv...
