Hi,
I am going to use user routine in DEFORM, however, I heard that I still need to install a software as a complier called ABSOFT. I wonder if anyone knows what to do after I installed the ABSOFT.
Btw, can ABSOFT act as a Fortran complier individually just as Intel Fortran in Visual studio?
Thanks a lot in advance!
Best wishes,

Hi,
I have a 0/90/0 rectangular laminate (all 3 D solid elements) . When I plot a through thickness shear stress S13, I want to know if the results are in the local coordinate system or the global coordinate system x-y-z.
Dear Colleagues:
As part of the USNCCM13, we are organizing a mini-symposium on “Peridynamics and its applications”.
This mini-symposium focuses on the recent developments of peridynamic mechanical and mathematical models and its applications on the solution of multiscale and multiphysics problems including damage and fracture as well as numerical solution methods. Other non-local models are also welcome.

Dear colleagues,
Consider a simple non-linear elastic material with stress given as
σ = D(εdev) εdev + B εiso
where εdev is the norm of εdev, D is a function of εdev and B is constant. The material is isotropic since the principal directions of σ and ε will coincide.
The department of Aerospace Engineering at Embry-Riddle Aeronautical University is currently looking to fill a position at the Associate or higher level in the area of structures. The candidate should have an exemplary record of teaching and scholarly activities including externally funded research. The candidate should be able to teach our structures and fracture mechanics classes at the undergraduate and graduate levels.
A poroelastic material can imbibe solvent and swell. When the material swells inhomogeneously or
swells under external constraints, stresses can develop inside the material. The stresses can trigger
mechanical instabilities in the material or even break the material, which have been often observed
in experiments. In this paper, we study the wrinkling instability of a circular poroelastic plate, in
the process of solvent molecules migrating into the plate from the edge. The critical conditions for
Two solids can adhere to each other in the presence of a liquid bridge between them, which is called wet adhesion. When the solid is soft, the liquid bridge can cause deformation in the material, and in turn, the deformation may have dramatic effects on the wet adhesion. To investigate the effect, in this article, we calculate the deformation in two soft layers with different separations and connected by a liquid bridge. We illustrate the effect of deformation in the soft layers on the adhesive force.
Cavitation can be often observed in soft materials. Most previous studies were focused on cavitation in an elastomer, which is under different mechanical loadings. In this paper, we investigate cavitation in a constrained hydrogel induced by drying. With taking account of surface tension and chemo-mechanics of gels, we calculate the free energy of the system as a function of cavity size. The free energy landscape shows double-well structure, analogous to first-order phase transition. Above the critical humidity, a cavity inside the gel is tiny.
