ABAQUS

We are looking for a PhD student for a research project on textile modelling. In this project, the main purpose is to develop a multi-scale textile modelling framework that allows accurate simulation of textile manufacturing processes such as yarn unwinding from a bobbin, weft insertion during weaving, stitching and tufting. This framework is implemented using finite element modelling as well as virtual fibre modelling. Key here are the dynamics of these systems as most textile production happens at high speeds.

Dear all,

I would like to ask you for advice. I am about to simulate a pull-through test (see attached picture) of a cladding panel made of a material with highly viscoelastic behaviour. I have parameters for Maxwell model (Prony series) obtained from test. I expect large deformation and probably cone failure (or tearing of the cladding panel). Therefore I would like to use Abaqus/Explicit. The problem is that I cannot use *visco step together with Explicit. Is there any way to solve it?

I am new to crystal plasticity simulations and have been studying the concepts from "Introduction to Crystal Plasticity" in Mechanics of Microstructured Materials book.

I am learning crystal plasticity and its implementation as VUMAT subroutine from the book Nonlinear finite elements for continua and structure. I am aiming to gain more insight about the implementation by studying the poly-slip, rate-dependent, single crystal plasticity subroutine provided in the solution manual.

However, I couldn't reproduce the example in the book successfully, as I believe I have made errors in defining the material properties in the Abaqus input file. So, can someone please provide the input file for the associated VUMAT subroutine?

Wire Arc Additive Manufacturing or WAAM techniques are attracting interest from the manufacturing industry because of their potential to produce large metal components with low cost and short production lead time. This process exists alongside other high deposition rate metal AM technologies such as powder and wire based DED. While these use either laser or an electron beam as energy source to melt a metal powder or wire, WAAM technologies melt metal wire using an electric arc.
