sir,
can u pls give the relevelent imformation to model the composite structures using fea packages like abaqus and hypermesh

New Generation CAE system for framed structures
Dear Colleagues,
I would be glad to present symbolic-numeric CAE system for frame structures analysis.
It will be available soon as Preview version for enthusiasts
The main features are:

Hi all
I am M.Sc. sutdent in Istanbul Technical University and my research subject is comparision of several ductile damage models both computationaly and experimentally.
I am trying to compare ductile damage models such as Freudenthal,Cockroft,Ayada ,Brozzo etc. computationally using ABAQUS and seeking a way to implement these damage models in ABAQUS.
To obtain each models damage result individually should damage model be implemented in ABAQUS or can a regular tensile test results be used for calculation of damage values.

What's that Car Noise? New SIMULIA Tech Brief Available: NVH Analysis with Rolling Tires
The sources of noise in a vehicle are many, including the engine, driveline, tire contact patch and road surface, brakes, and wind to name a few. A Noise, Vibration, and Harshness (NVH) engineer is tasked with predicting these noises early in the design phase to make the necessary adjustments to ensure a harmonic ride, so to speak. The latest SIMULIA Tech Brief illustrates the effects that rolling tires have in contributing to NVH.

energy balance of surface-based cohesive of composite under impact in Absqus 6-10
Hi there! I am really new to Abaqus and I need to model a composite
laminated crash cone under impact to a flat solid wall (analytical
surface is used). I modelled a cone with a layers of conventional shell
elements with hashin failure criteria and surface-based cohesive
behaviour as interaction between layers representing the interface of
composite laminates. The model runs successfully but once I checked the
energy balance, the damage dissipation energy from the cohesive, it
turned out to be NEGATIVE (I think this is wrong).
