Hi,

I am trying to model asphalt concrete as viscoelastic mayterial in abaqus. As I have seen from past studies, people have used prony series parameters for time domain viscoelasticity and additionally also used elastic modulus from resilient modulus test data. As I already have dynamic modulus test data, I can calculate prony series parameter from it but the problem is with resilient modulus. Do I need to run resilient modulus test again to get the elastic parameter in abaqus or is there any other way to work with dynamic modulus test?

hello

i simulted impact on ceramic plate but after the impact the element of ceramic didnot erod. i use element deletation=yes, any body know what should i do?

thanks

Sir,

I am facing the problem in Ansys 13.0 for making functionally gradient material plate where E (youngs modulus) can vary as per thickness of plate 

kindly suggest me how to model the plate 

Dear All,

As a part of my PhD project I need to implement the tangent stiffness matrix of a 2D beam co-rotational formulation.

 So I will apreciate if somebody can show me the components (coefficients)  of the element tangent stiffness matrix.

Thanks in advance

My thermal simulation in the alternator required convective coefficient . Presently i have computed convective coefficient for stator,rotor,rectifier assembly by thermal testing at steady state condition. I have completed thermal simulation for these components of the alternator . Next, i want to perform thermal simulation for entire alternator.Is there anybody, provide me guidance to formulate correlation between geomentry,ambient condition,convective flim coefficient.Further, i have to model contact among components in the alternator. it requires thermal contact conductance.
