FRacture Growth - Abaqus Explicit

Submitted by satyasrinivas on
Choose a channel featured in the header of iMechanica

Hi,

        I want to model 3D crack propagation in Abaqus Explicit. For this I am thinking of using the *shear failure option with element deletion. The path of the crackin my models is not known. I have some basic questions in this regard.

 

1. Is *shear failure a good approach to model crack propagation ?

 

Seeking a logarithmic operator for a 4th order tensor

Submitted by wvmars on

I don't know whether this question has an answer, but I'd like to see what you all think:

Does anyone know whether or not the following operation is meaningful, whether it is described and defined algorithmically somewhere, and / or how to do it?

ln(Aij) = Bkm ln(Cijkm)

A and B are second order tensors

C is a 4th order tensor

The left hand side involves the natural logarithm of the 2nd order tensor A, which is no problem. 

Problems with FEAP compilations in Visual Studio 2008

Submitted by jretamav on

I have a problem when a try to compile FEAP with visual studio 2008. The error is the next:

error #6633: The type of the actual arguments differs from the type of the dummy arguments.

I have tryed to compile several times but the error is the same.

I do not know if I have configure properly my visual studio or if it is a problem with mi FEAP.

 

Thank you very much.

Calculation of potential energy in conditions of prescribed displacement and prescribed loading

Submitted by Liu Jinxing on

A question has arised when I read a book about fracture mechanics recently.

This question is about the calculation of potential energy in "fixed-grips" (prescribed displacement) and "dead-load" (prescribed displacement).
