Nine papers about fatigue modelling of short fiber composite

Submitted by Atul Jain on

Recently, we have published a series of nine papers about modelling fatigue and damage in short fiber composites.  Together, they provide a complete description of modelling of such materials including wavy fiber composites; starting from appropriate homogenization method to component level fatigue simulation. Discussion and feedback on the papers is welcome.

Writing UHYPER for photo-thermal sensitive hydrogels described in the thermodynamic framework?

Submitted by Arash Krg on

 Hello

I`d like to write a UHYPER for photo-thermal sensitive hydrogels described in the thermodynamic framework. But the photo-chemical term in the energy equation is 7order greater than the others. The other terms are related to stretch and mixing energy they exist also in the temperature sensitive hydrogels energy equations and their UHYPER is valid.  I have checked all the coefficients, their orders are all correct.

Is it something wrong with modeling, or I have made a mistake?

Dear All,

for LCF analysis to get crack initation life for simple plate with central hole specimen.

I used direct cyclic approach but getting error as o/p "CYCLEINI" is not available for your element type.

with fe-safe fatigue tool i got the crack initiation life but I want to get with Abaqus/CAE only

kindly help me out.

how to obtain the crack initation life using abaqus only.

Thanks in adavance

 

Finite element analysis of beams

Submitted by Arifdjanov Abdulla on

In this section, the basic principles of the finite element analysis of beams are considered. Beam given below we will divide into two elements by cutting it at the point A, B, C

 

We will make the equilibrium equations  nodes A , B, C . Equations are written so that you can clearly see the contribution of each element. For each element can define a list of indices. list of indices indicates in which equations contributes each element..

Hallo,

from this month i am going to start my work on Discrete Element Method. I am totally new to this field. Therefore, i am looking for some material which can help me not only to understand the theoretical concept but as well as the programming concept in this field.

 

I will be very thankful if someone have materials related to DEM.
