Steel metal forming using polymer composite rapid prototype tooling
Article Abstract:
A computer-aided method to estimate the fatigue life of a sheet metal forming die fabricated from aluminum trihydrate (ATH)-filled polyurethane was presented. The engineering data were obtained by characterizing the material in various perspectives: microstructure, mechanical and fatigue behavior, and terminological properties.

Elastic and inelastic recovery after plastic deformation of DQSK steel sheet
Article Abstract:
Strain recovery after plastic prestrain and associated elastic and inelastic behavior during loading and unloading of Deep-drawing Quality Special Killed (DQSK) steel sheet are measured. It is found that modulus decreases with increasing loading stress, while Poisson's ratio shows the opposite trend.

Off-axis torsion tests on tubular specimens of steel
Article Abstract:
An off-axis torsion test by combined loading is developed to analyze the anisotropic hardening behavior of metals. The experiments have verified that anisotropy is more severe when a smaller offset strain is used in defining the yield stress.
