i am a student of Msc in structural engineering. currently i have been involved in the research of "shear behaviour of RCC beam column joint ".
Hi, dear all,
I am facing problem on differentiating left Cauchy deformation tensor and right Cauchy deformation tensor.
thanks for notes in http://www.engin.umich.edu/class/bme456/ch3strain/bme456straindef.htm, i can derive the them in terms of mathematical equation, but i cannot differentiate them in engineering modelling filed.
From what i read is
Dear all,
I recently need calculate the stiffness matrix of the cohesive elements manually via mathematica. I used the finite element method to fulfill the assignment, but the result I got didn't match the stiffness matrix I extracted from the Abaqus. Neither did my supervisor.
knn, ktt and kss seem to be so obvious for the traction-seperation law, as also it measioned in Abaqus. Could you please help me out by offering the way to find how the ABAQUS exactly design the cohesive elements or how ABAQUS calculate the stiffness matrix.
hi,
i am modelindg a concrete beam , first i creat one concrete element and then copy it to creat the beam, but how can i add the steel, i dont want the steel nodes to be coincide with concrete nodes, and then how can i add combin39 between steel nodes and concrete nodes.
thanks
Prony series form :
gR(t)= 1- ( sigma(i=1to N)(gi(1-exp(t/τi))))
where,
gi= Shear relaxation modulus ratio
τi= Relaxation time
can anyone provide me the prony series upto 3 to 4 term for epoxy resin material....its urgent.
Hi all,
Our research team took part in the conference "Sustainable Solutions for Concrete Structures", which took place in Aix-en-Provence, in France. The conference was dedicated mainly to recent advances in modelling of concrete and concrete structures. As always, more details can be found on: microlab-m3c4.blogspot.com
Cheers!
Dear All members
I would like to ask if any one can provide tutorials on NURBS subject related to coding in matlab ?for example matlab codes about thin plate with hole or cantilever beam problem.
Thanks

Hey everyone,
I'm very new on Abaqus, and what I'm trying to do is to assign to a model a changing E modulo as a linear function of Z coordinate ( E(Z)=-33936.651*Z+25e06 ).
I tried to gather some knowledge over the web on how to do so, and I found out that It can be done by writing a USDFLD subroutine, I managed to pick of some exapmles the following code:
SUBROUTINE USDFLD(FIELD,STATEV,PNEWDT,DIRECT,T,CELENT,
1 TIME,DTIME,CMNAME,ORNAME,NFIELD,NSTATV,NOEL,NPT,LAYER,
Hi everyone,
I was having problems in loading previously saved files in CATIA V6. I tried searching for a solution, but nothing has come up till now. If anyone can help me on this, Please reply.!
Thanks in advance.
