3rd International Conference on Material Modelling incorporating the 13th European Mechanics of Materials Conference

Submitted by mmazdz on Thu, 04/11/2013 - 16:22

Dear Colleagues,

During the last decades material modelling has become a field of central

scientific importance. Although there exist many workshops, meetings,

colloquia, etc. on specific materials, and particular applications, here a

single conference dedicated to material modelling with all its various

facets is intended. To this end, the aim of the ICMM conference is to bring

together researchers from the various fields of material modelling and

materials characterization. The intention here is to cover essentially all

Easily calculate longitudinal compression strength of unidirectional composites

F1c

The longitudinal compression strength of unidirectional composites F1c, also called Xc, is very difficul to test for, so often you don't have the value for the particular material (fiber, matrix, volume fraction) that you wish to use. Further, just having data does not tell you what paramaters really influence its value--it is not the compressive strength of the fiber, I can assure you. So, there is a simple formula that you can use to predict its value and also to understand what are the parameters that really affect the compression strength of the composite.

How to find material parameters for Abaqus PDA

Submitted by ebarbero on Thu, 04/11/2013 - 07:08

ABAQUS

composite materials

ABAQUS/CAE

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.

ABAQUS

composite materials

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.

lack of convergence

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.
