Friction modeling LAMMPS
Hi All,
Is there any one working on modelling of friction using LAMMPS to discuss an issues?

Add XFEM crack to an already deformed model
I hope this can be done and I want to say thank you in advance for any feedback.
I have already completed a simulation of a plate with a hole and pulling a mandrel through the hole to expand it and create a plastically deformed hole.
Now, I would like to take this plastically deformed hole, add an XFEM crack and vertically pull to simulate a tension test.
Can this be done?

Unconditionally stable explicit method
Hi every one,
I have recently seen some papers that claim to present an unconditionally stable explicit time integration method.
Is it (mathematically) possible to do such a thing?! I though that all explicit methods are atmost conditionally stable.
A constraint-free phase field model for ferromagnetic domain evolution
A continuum constraint-free phase field model is proposed to simulate the magnetic domain evolution in ferromagnetic materials. The model takes the polar and azimuthal angles (ϑ1, ϑ2), instead of the magnetization unit vector m(m1,m2,m3), as the order parameters. In this way, the constraint on the magnetization magnitude can be exactly satisfied automatically, and no special numerical treatment on the phase field evolution is needed.
Ansys workbench modelling problem
Hi
I'm a mechanical engineering working on modelling composite in ansys workbench. I have a problem in modelling a composite plate with ACP. To do this, i created a static structural and modeled a surface body of a plate and after applying loads and boundaries, i attached to it an ACP(Pre). The procedures has been done like Tutorial 1 of ACP of ansys workbench 15.
Postdoc in Mechanical Engineering (new graduate June 2014)
Hi everyone I'm looking for a postdoc in Mechanical Engineering, I prefer the domain of Composite and Heterogeneous Material Analysis and Simulation.
I'm seeking for your advices for a good application, and for Postdoc propositions.
Thank You for all.
Journal Club Theme of January 2015: Topology Optimization for Materials Design
Processing technologies are rapidly advancing and manufacturers now have the ability to control material architecture, or topology, at unprecedented length scales. This opens up the design space and provides exciting opportunities for tailoring material properties through design of the material’s topology. But as seen many times in history with advancements in materials and processing technologies, the natural default is to rely on familiar shapes and structure topologies.
