ENF specimen
Cohesive layer

Hi Everyone,

                 I am new to abaqus and I am modeling an ENF specimen in abaqus..I am trying to find some tutorials relating to ENF specimen model in internet but i couldn't find one till now..If any one having the experience of modeling ENF specimen in abaqus kindly help me by providing some of the materials regarding this.

gradient of deformation in skeletal muscle

Submitted by farhadmir on

finite element

Dear All

My thesis is about finite elment modeling of skeletal muscle in which I should calculate gradient of deformation incrementally in ABAQUS subroutine "UMAT".

However,for starting the code to perform having initial deformation gradient is essential. I don't know how to start the program.

Would anyone familiar with this field help me or introduce any reference.

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

plate theory
variational asymptotic method

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

model residual stress relaxation

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.

RVE
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.
