The auxiliary fields could be applied to the method for computation of SIFs for a dynamically propagating crack
Forums
Hi all,
Recently, I have read the paper "Dynamic crack propagation under mixed-mode loading- Comparison between experiments and X-FEM simulations" published in IJSS, 44 (2007), 6517-6534. I have met some questions on the choice of auxiliary fields for calculating the SIFs. Could someone give me some details including the auxiliary velocity fields, the auxiliary displacement fields and the auxiliary stress fields. Thanks.
regards

sir/madam,
i have modelled a curved section with one end fully constrained and to other end applied pull load, i am getting result in cylindrical co-ordinate system can i see the results in cartesian co-ordinate system

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
how does ABAQUS design the cohesive element
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.
how to use combin39
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
Required prony series of Epoxy Resin
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.
SSCS 2012
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!
