Finding the stiffness component C11 of a composite material under axial tension?

thread727-432265

Finding the stiffness component C11 of a composite material under axial tension?

Finding the stiffness component C11 of a composite material under axial tension?

(OP)
By using the ABAQUS FEA software I am trying to find a component of the effective stiffness matrix, C11, by applying a tensile load to a composite material that is comprised of two different materials. I have successfully set up the geometry, applied the boundary conditions, and load. However, I am lost when trying to figure out how to figure out what I need from here. Is there a certain method to follow to figure out the modulus in a certain direction?

RE: Finding the stiffness component C11 of a composite material under axial tension?

Modulus = applied stress divided by the resulting strain calculated by the model

RE: Finding the stiffness component C11 of a composite material under axial tension?


In the specific material specification properties founder at the keyword "MATERIAL" for *ELASTIC specify the range of values of E and the corresponding shear strain values in the ascending order.
The Modulus and DEPENDENCIES parameter is shown in ABAQUS FEA specifies the number of field variables that is currently in used. Using the current user subroutine FIELD, you can accurately specify the specific Field variable value to be the calculated deviatoric value of the shear strain.
