Abstract: The paper presents the development of a localized necking criterion based on the singularity of acoustic tensor. This criterion is applicable to materials exhibiting strain-softening behavior. The ...

Abstract: This paper presents the development of a generalized method to predict forming limits of sheet metals. The vertex theory, which was developed by Stören and Rice (1975) and recently simplified ...

Abstract: This paper presents an investigation on forming limits of tailor-welded blanks (TWBs) made of 5754-O aluminum sheets using both experimental and numerical approaches. TWBs may be composed of two ...
