Postdoc position – Modeling dynamic fracture and fragmentation

Submitted by ndaphalapurkar on

A Postdoctoral fellowship is available at The Johns Hopkins University, Baltimore, U.S.A. in the area of fracture and fragmentation under dynamic loading conditions. The potential candidate should have a Ph.D. in an engineering discipline, a strong background in fracture mechanics and extensive computational modeling experience working with the finite element methods or some other numerical method with application to solid mechanics.

Barber, University of Michigan, as the recipient of the 2015 Ted Belytschko Applied Mechanics Award. This award will be presented at the AMD Honors and Awards Banquet, tentatively scheduled on Tuesday, November 17, 2015, during the ASME International Mechanical Engineering Congress and Exposition, to be held in Houston, Texas, November 13-19, 2015.

How to prevent non-physical interpenetration of particles

Submitted by nizanth on

Hi all, 

    I was trying to simulate the mode 2 delamination using End loaded split test using meshfree method (RKPM) by coding in MATLAB.  Traction separation law is implemented.

When upward load(displacement controlled)  is applied at the bottom portion of the bottom lamina, the bottom lamina is penetrating into the first lamina. At the surface where contact is happening, there is no traction transfer happening.

In ABAQUS, we can define a contact surface and interpenetration can be prevented, ensuring traction transfer.
