TL;DR: In this article, the authors developed a theoretical study on forming limit diagrams using a new general code for forming limit strains prediction, which consists of the main part and several subroutines, which allow the implementation of any hardening law, yield function, or constitutive equation, changing the respective subroutine.

TL;DR: In this paper, carbon nanotube reinforced copper matrix (CNT/Cu) nanocomposites were fabricated by the modified molecular-level mixing process, which produces a homogeneous dispersion of CNTs in a fine grained metal matrix.
Abstract: Carbon nanotube reinforced copper matrix (CNT/Cu) nanocomposites were fabricated by the modified molecular-level mixing process, which produces a homogeneous dispersion of CNTs in a fine grained metal matrix. These nanocomposites, consisting of 1.5μm Cu matrix grains and 5vol% of multiwall CNTs, show a high strengthening capability; enhancing the yield strength of unreinforced Cu by 2.3 times. The enhanced yield strength stems from the reinforcing effect of CNTs and additional hardening of the Cu matrix by grain refinement. The results reveal that the metallurgical treatment of the matrix is important for the development of high-strength CNT/metal nanocomposites.

TL;DR: In this paper, a double yield surface constitutive model is proposed based on the triaxial compression tests in order to describe the deformation properties of frozen saline sandy soil, which contains the influence of salt contents on mechanical characteristics.
