Hi All

I am trying to obtain SIF value for a stationary crack using XFEM in Abaqus.

I am using the 5th contour value and plotting against distance from crack front using excel.
The values are from History Output.

 I am getting a very funny graph that is going up and down.

New Ebook on Elastic Solids at Amazon

Submitted by Carl T. Herakovich on

This treatise provides a broad overview of the definitions of
fundamental quantities and methods of analysis for the use of solid materials
in structural components. The presentation is limited to the linear elastic
range of material behavior where there is a one to one relationship between
load and displacement.  Fundamental
methods of analysis and typical results for structures made of elastic solid materials
subjected to axial, bending, torsion, thermal, and internal pressure loading;

Eulerian Analysis in impact phenomena

Hi friends,

 Does anybody know what this error mean?

The general contact definition is empty. The definition must include at least one surface. If *CONTACT EXCLUSIONS was defined, check whether the *CONTACT EXCLUSIONS option was specified correctly. Additionally, check whether PURE MASTER-SLAVE formulation is applied to any self-contact situations.

Abaqus Help

Submitted by swhww3 on

Hello everyone. I am new to Abaqus and was wondering how to create a model of a heat sink mounted on a heated silicon dioxide substrate. The substrate is on the left side and is a rectangle with a height of 40 mm and width of 5 mm. The heat sink is connected to the right of that with a parrellelogram shape, left side height of 40 mm (adjacent to the substrate), and right side parallel with a height of 5 mm. If anyone can help it is greatly appreciated. When I try modeling it, during section assignments it will not allow me to assign any sections. I have attached a picture of the model.
