Procedure for the determination of true stress-strain curves from tensile tests with rectangular cross-section specimens
Article Abstract:
The finite element analyses are used to determine the true stress-strain curves from flat tensile specimens beyond the onset of necking. The results of the numerical studies and the deduction of the analytical relation, which is applied to a micro-flat tensile specimen out of a ferritic steel plate, are presented.

Ultimate strength and failure mechanism of resistance spot weld subjected to tensile, shear, or combined tensile/shear loads
Article Abstract:
The objective of the study is to develop an engineering failure criterion for spot weld in thin sheet metals under nugget pullot mode. The strength test using cross tension and lap-shear samples made of high strength steel is performed to develop the failure criterion of spot welds.
