Applying load on a Compact Tension specimen in Abaqus

Submitted by Chizyuka on
education

Hi there,

I have been trying to model fracture toughness test in abaqus but unfortunately I am faced with difficulties of how to apply the tensile loading on the compact tension model's pin holes. Most papers I have come across show only pressure being applied on the flat upper most edge of the test specimen instead of the pin holes. Please could there be someone out there who could show me how to apply this tensile loading right on the holes?

Thanks in advance.

A postdoctoral position is available immediately at the Department of Biomedical Engineering, Johns Hopkins University for work on a project simulating cardiac mechanics in normal and failing hearts. A PhD in Mechanical or Biomedical Engineering or related field is required. The candidate is required to have strong expertise in modeling soft tissue mechanics. The  successful candidate is expected to be able to develop code to simulate the contraction of the heart as well as to conduct simulation research on abnormalities in cardiac contraction. Send inquiries to Dr. N.

Running the *.psf file in ABAQUS/CAE

Submitted by imangolzad on

Hi all,

I want to use abaqus for parametric study. I have the input file (*.inp) and the python scripting file (*.psf). The problem is that I do not know how to run the *.psf file. I tried the command abaqus script=myfile (the myfile is the file with psf extension) but the error massage (Invalid Syntax) appears.

I would appreciate it if anyone help me to run the *.psf file. Is there any other way rather command line to execute the python scripting file such as *.psf files?

Thanks. 

Nonlocal Instability Analysis of FCC Bulk and (100) Surfaces Under Uniaxial Stretching

The objective of this paper is to examine the instability characteristics of both a bulk FCC crystal  and a (100) surface of an FCC crystal under uniaxial stretching along a <100> direction using an atomistic-based nonlocal instability criterion.  By comparison to benchmark atomistic simulations, we demonstrate that for both the FCC bulk and (100) surface, about 5000-10000 atoms are required in order to obtain an accurate converged value for the instability strain and a converged instability mode.  The instability modes are fundamentally different at the surface as comp

Recent advance in adaptive remeshing techniques now gives the possibility to efficiently simulate complex 3D crack growth using conform meshing of the discontinuity. An exemple of such kind of mixed mode simulation with adpative remeshing can be seen on YouTube:
