The PDA model implemented in Abaus is an implementation of the idea of the cohesive zone model (CZM), which is quite popular for the analysis of delaminations, but PDA is for intralaminar damage. The problem my group faced when trying to use PDA was "where do we get the material parameters?" We asked around in blogs and such but could not find a definitive answer. So, we went to work and came up with a methodology that may serve you.
New textbook includes an explanation of the concepts involved in the detailed analysis of composites, a sound explanation of the mechanics needed to translate those concepts into a mathematical representation of the physical reality, and a detailed explanation of the solution of the resulting boundary value problems by using commercial Finite Element Analysis software such as Abaqus.
Using Abaqus, hanging some mass in Truss element (T3D2), facing numerical singularities and lack of convergence due to Truss elements have no initial stiffness to resist loading perpendicular to their axis. If a stress-free line of trusses is loaded perpendicular to its axis in Abaqus/Standard. Kindly suggest me how to overcome this.

Research Studentship (PhD) in Computational Material Science: the topic is computational nano mechanics and concurrent multiscale methods for composites under impact loading.
Any one help me out ,How to estimate stiffness matrix of beam using modal experimental method?
Hi,
i'm in an internship, and i want to study the stress destribtuion with photoelasticity method, but my problem is that the material that i have is not homogenious but there ares two layers. I can do the measurement for the two material separated, but i dont know how to do that for my layared material.
anyone have an idea about how to do photoelasticity measurement for multilayere materials ?
Thanks.
Dear all,
