Hello colleagues.
I am solving a ring as an axisymmetric solid. I apply displacements and define reactions. According to an experimental data calculated reactions twice larger. We think it because the ring is thin and it is too rigid in solid formulation. Did anyone see solid formulation with a rotational DOF, i mean in any other FEA products?
This paper studies the poroelastic behavior of an alginate hydrogel by a combination of theory and experiment. The gel—covalently crosslinked, submerged in water and fully swollen—is suddenly compressed between two parallel plates. The gap between the plates is held constant subsequently, and the force on the plate relaxes while water in the gel migrates. This experiment is analyzed by using the theory of linear poroelasticity.
Hi all,
I am conducting some cohesive crack simulations within the framework of XFEM. The cohesive model is an initially rigid traction-separation law for mode I. In order to deal with negative values of the normal sepration/jump, I use a penalty stiffness K.
Hi
I have a problem with applying periodic boundary condition. I have used *EQUATION in constraints for opposite nodes and surfaces. But I still have some problem with that for sure I making some simple mistake. If anyone could look at my model and find problem. Abaqus version 6.9-1 .
Thanks a lot.
This paper uses a method based on indentation to characterize a polydimethylsiloxane (PDMS) elastomer submerged in an organic solvent (decane, heptane, pentane, or cyclohexane). An indenter is pressed into a disk of a swollen elastomer to a fixed depth, and the force on the indenter is recorded as a function of time. By examining how the relaxation time scales with the radius of contact, one can differentiate the poroelastic behavior from the viscoelastic behavior. By matching the relaxation curve measured experimentally to that derived from the theory of poroelasticity, o
hello my dear friends
i have a small problem, being fresher in ANSYS i couldnt solve the buckling problem can any one help me out
i have made the following APDL text
Dear all,
I did a 3 pt bending impact simulation with an elasto plastic model. But the slope of contact force vs time curve is too steep at the beginning of the impact. One trivial way of reducing the slope is by reducing the young's modulus of elements in the vicinity of contact or the impactor. Also reducing the mass of the impactor and the impact velocity did not help in reducing the slope.
Is there any other non-trivial parameters that controls the slope of contact force vs time plot? Thanks ina dvance.
I solved the mode shape of the clamped-pinned boundary conditions, a undefined parameter, 'c' is appearing in the mode shape of the coloumn.
Query:1) Could anyone would like to discuss on this undefined parameter, 'c'. it is critical to define the final modeshape of the column.
Non-linear buckling.
