Hi all,

I am trying to replicate an analysis done in Abaqus by using LS Dyna. I've an input(inp) file of the abaqus model on which the analysis has been performed.

hi every body..

im trying to  model interface delamination in ansys. i use inter204 or 205 for interface element.the problem is that as the stress in interface riches the yield value, the solution doesnt converge.

i tried to increase  the number of substeps or decrease the size of element, but the problem still exists.

There is an immediate opening for a postdoctoral research position in the Advanced Computational Research Lab at RPI, Troy, NY to work on a multiscale modeling project which involves modeling of radiaiton damage of metallic materials. Encouraged to apply are creative, self-motivated candidates with a sound background in computational mechanics. Desired qualifications: (1) PhD in Computational/Applied Mechanics/ Materials Science.

Hello I am a student of the University of Manchester. I am modelling a SHPB assembly together with the specimen, and I am having trouble with placing the loads,creating the boundary constrain between the incident, transmitter bar and the specimen. I created the interaction between the assembly with a suppressed TIE, and after loading and submitting the job I kept on getting errors. The load did not transmit to up to a quarter of the incident bar.

My research field is Numerical methods in fluid dynamic. The method that we use named CDLS mesh-less method. It is based on MLS shape function and Least square equation discretization.

We decide to change our shape function from MLS to RPIM. We predict if this shape function couple with our method, we will reach better results in fluid dynamic problems. But we don't have any experience in using this kind of shape functions.

Now I am looking for a person who has experience in working with RPIM shape function for cooperation.

Two PhD studentships opportunities are available at the Universite catholique de
Louvain in Belgium for outstanding candidates.
The aim of the project is to develop a novel approach for generating
dominant hex meshes for general/complex 3D models. The approach will be based
both a generalisation of Lloyd's algorithm and on the resolution of some kind of
PDE in the domain in order to compute distances, curvatures, surface
geodesics... We look here for an indirect approach i.e. we first generate the
points and then reconnect them. All the developments will be done in the
framework of gmsh (http://www.geuz.org/gmsh).
Successfull candidates should have a strong background in applied
mathematics/numerical methods for CFD. Some knownledge of mesh generation

Please share some views on manipulation or controlling the behavior of the phonons. How can we make it possible.?

THE JOB POSITION HAS BEEN FILLED. PLEASE DO NOT SEND APPLICATION.
