Modelling ENF specimen with cohesive elements in Abaqus

Submitted by jayhars on

Hi Every one,

                  I am doing my master thesis in mechanics in the subject of fracture mechanics.Now i need to create a ENF specimen in Abaqus for evaluate my experiment results.I am new to abaqus, so i need  your help to create the ENF specimen in abaqus.I have some data to create the model and it is as follows

Three ways to derive the classical plate model

Submitted by Wenbin Yu on

Attached is part of my lecture notes for a graduate structural mechanics. In

the notes, we derived the classical plate theory, which is also called

the Kirchhoff plate theory, in three ways: Newtonian method, variational

method, and variational asymptotic method, using 3D elasticity theory as the

starting point. The self-contradictions of Kirchhoff assumptions and plane-stress assumptions used in both

Newtonian method and variational method are clearly pointed out. The

I am doing one project regarding simulation of modeling residual stress relaxation for AA2024-T351. I am having trouble in introducing cyclic loading for the material. what are the steps needed to do this simulation? i have attached the workpiece dimensions. 

Homogenization technique

Hello all,
 
Why is there no body force considered in the equilibrium equations of the RVE in the homogenization technique?
 
The overall response of the RVE is obtained by solving the RVE boundary value problem under prescribed boundary conditions (either traction or displacement BC) without considering the body force.

Hi

I was modeled a frame @ 6 plates that this plates must be attached to the below frame by some plastic nonlinear translational spring

the specification of this springs ( force-displacement curve) is available & this propety must be define to springs in abaqus model. I can not find this spring in abaqus ,define this propery .hepl me pease to solve this problem.

thanks alot
