Hi
The question is coupling the Gurson model with the crack propagation on a CCP specimen with Abaqus. Then a study of the influence of parameters of the Gurson model J-intgrale And deduct the best set of the parameters with we can adjust the JR curve computed on the experimental curve
Hello all,
I would like to seek help on a topic on which I am slightly ignorant.
I do not understand the concept of non local damage and the internal length of the non local continuum as described by the well quoted paper of Pijaudier-Cabot and Bazant (1987) in continuum damage mechanics. So may I please ask the experts in this forum to please explain to me using some simple analogy.
Dear all,
According to polymer theory, the relaxation time depends on its length (or unit number), and there exist some relationships to describe such dependence. The smaller number of polymer units, the smaller the relaxation time of the polymer is. How to describe this via a simple model of visco-elastic springs?

Hi everybody,
I have designed a composite made up of woven fabrics in CATIA v5 and imported to the ABAQUS. While meshing the 8 parts, I saw that any of the two surfaces having interfaces with each other, have different elements and nodes while there should be the same elements and nodes (meshes) at their interfaces. What should I do in meshing module to solve this problem?

A thin film subject to compressive strain can either bend (for large strain gradient) or wrinkle (for small strain gradient). The bending is traditionally used in thermostats (bimetal stripes), but couple of years ago, it was extended to the nanoscale thin films which can bend and roll-up to tubes with defined number of rotations. The wrinkles are also rather common in macro- and microscale thin films.
Here, we developed an equilibrium phase diagram for the shape of
compressively strained free-hanging films by total strain energy
minimization.
