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:

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.

 sir i am doing my m.e project in fracture mechanics . from baground of civil engg i want to now how to model three point beam bending with crack in ansys plse help me

hello

dear vinh phu nguyen

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).

Why are quad elements better than tria elements in fem/ cae analysis?

Hi all

         I want to know how to find nodal stresses. For example say, in a plane stress analysis knowing displacement's dof, we can get stresses. But these stresses are those at the Gaussian points. We can extrapolate these stresses at Gaussian points to nodal values. My question is, for every node we will get four stresse values (extrapolated from stresses at Gaussian points) using these how I can get single value at the node? What averaging techniques I should follow and how ? And after finding a single stress at a node, how we can get stress for the element? 

Hello
I am a Mechanical Engineering
student. I
am working on a vibration project . i want to help us to use ansys very well and solve problems.

i am doing about creep response of wood/PVC composite beam by ABAQUS. and now there is problems to find the value/paremeters fill-in the creep mode such as Power law multiplier, Eqstress order, Time order. and other reccomend

please look at a attached file.

Thank you

Hi. 

About the 1st Eq...

I don't know mean of conlon(:).

How do I use formulation  for constructing stress- train diagram from Hopkinson pressure bar device at high rate of loading?
