I have two questions concerning strain in Abaqus:
1. In Abaqus CAE, the user can only specify as boundary conditions the applied displacement and time. So how does Abaqus calculate the applied strain and strain increment, especially for non-linear problems where the relation between displacement...
This question has been in my mind for a long time: as we know, finite element method is a numerical technique for solving partial differential equations. So, as a finite element software, what underlying partial differential equations does Abaqus solve?
Hi hansini,
Yes I was doing a non-linear analysis. So you mean I should plot the stress-strain curve from LE33 and S33 of each element, rather than from the force-displacement relation of the reference point?
Hi all,
How to plot the overall stress strain curve for multiple elements? For example, I'd like to simulate the deformation of a material. The mesh consists of 1000 elements. When the calculation completes, I want to extract the overall stress-strain curve for the whole model (1000 elements)...
Hi all,
If there is grain that is 1000 nm in length and 10 nm in height, and in Abaqus I use a C3D8R element with 100:1 aspect ratio to simulate the grain. Now, if there is another grain that is 2000 nm in length and 20 nm in height, and this time in Abaqus I make the element twice as long and...
