A single strand of polymer is a chain of a large number of monomers. The monomers are joined by covalent bonds, and two bonded monomers may rotate relative to each other. At a finite temperature, the polymer rapidly changes from one configuration to another. When the two ends of the polymer are pulled by a force, the distance between the two ends changes. The polymer is known as an entropic spring.

Ecole Polytechnique and McGill are seeking two PhD candidates for a large project aiming at understanding the effects of shot peening on the fatigue lives of aerospace components. The project involves 8 PhD students that will be working in close collaboration. The project is co-funded by the Canadian goverment and 5 leading aerospace companies located in Montréal. Some projects involve internships at these companies.
We are seeking two students for the following projects:
I want to model a fiber rod pull out process in Abaqus. The fiber is a composite rod which is to be debonded first from the surrounding laminate and need to be sliding along the interface of the rod/laminate.
Modelling:
i created an axisymmetric model of the rod being surrounded by the laminate. i got the residual stress due to curing process. This residual stress is compressive at the interface which is responsible for resisting the pull out force applied at first.
loading:
Axial pull is applied at one end of the rod. and the other end being fixed.

Dear Colleague,
hi everyone,
please help in how to apply load in the form 10 sin pi x/a sin pi y/b for the static analysis of plate in ansys? here a and b are dimensions of plate and x=a/2, y=b/2. iam a beginner in ansys.
