Hello Sir,
My ABAQUS model has two parts:1.Projectile,2.Target. I have written subroutine for target.I want to use inbuilt johnson cook damage model for projectile.How to use subroutine only for the target in ABAQUS analysis?
I want to find the contour integral related to time, Ct, which characterises the near tip fieled in elastic nonlinear viscous materials in Abacus. What type of material data will be needed in Abaqus to carry out the computation? Please help.

We welcome applications for a post-doctoral position in the Multiscale Computational Mechanics Laboratory (MCML) at Vanderbilt University. MCML is a part of the interdisciplinary Multiscale Modeling and Simulation (MuMS) facility.
In order to improve the properties of metallic glasses (MG) a new type of MG structure, composed of nanoscale grains, referred to as nanoglass (NG), has been recently proposed. Here, we use large-scale molecular dynamics (MD) simulations of tensile loading to investigate the deformation and failure mechanisms of Cu64Zr36 NG nanopillars with large, experimentally accessible, 50 nm diameter. Our results reveal NG ductility and failure by necking below the average glassy grain size of 20 nm, in contrast to brittle failure by shear band propagation in MG nanopillars.
Abstract: Brittle materials propagate opening cracks under tension. When stress increases beyond a critical magnitude, then quasistatic crack propagation becomes unstable. In the presence of several precracks, a brittle material always propagates only the weakest crack, leading to catastrophic failure. Here, we show that all these features of brittle fracture are fundamentally modified when the material susceptible to cracking is bonded to a hydrogel, a common situation in biological tissues.

Dear Colleagues,
I want to share with you our work on geometric instabilities in thin films, which was recently accepted in Soft Matter.
