A method of correction and optimization of stamping processes is proposed. The experiment design and finite element methods are interfaced. This is applied on a part showing large springback. After the determination of the important process parameters to study, a fractional factorial experiment design is built and the corresponding numerical simulations are carried out. Their results are the de...
A validated numerical model for in-plane stress/strain prediction is essential in understanding the deformation behaviour of sheet metal forming process, in particular, asymmetric deep drawing of advanced high strength steel sheet. In this work, the Yld2000-2d anisotropic yield criterion integrated with the initial homogeneous anisotropic hardening model was employed to describe the complex mat...
VARIATION SIMULATION OF FIXTURED ASSEMBLY PROCESSES FOR COMPLIANT STRUCTURES USING PIECEWISE-LINEAR ANALYSIS Michael Leon Stewart Department of Mechanical Engineering Master of Science While variation analysis methods for compliant assemblies are not new, little has been done to include the effects of multi-step, fixtured assembly processes. This thesis introduces a new method to statistically ...
