    The CosmosWork show " Echeck"

    Please anybody help me, I try to run the simulation with CosmosWork proffesional 2005, but I received the error message with "ECHECK". I cant understand how to do with this, anyone could advise me! Thanks!

    Ask about material NZ/AS standard

    I have question as follows: 1. what is the equivalent material for AS 3679.1250 in ASTM? I cant find the material in website. Please help me! Thanks!

    The problem of FEA analysis with P-Adaptive method

    For the weldment for the hollow beam to other hollow beam, I found that I cant doing the fillet corner. The beam I definte in flat corner to represent the weldment, but the critical point concentrate at the flat corner. That is why I say the stress become higher and higher.

    The problem of FEA analysis with P-Adaptive method

    Thanks. I change the design to fillet. But there is still some point have the higher and higher stress concentration. why? May be I should ommit the point?

    The problem of FEA analysis with P-Adaptive method

    Yes, that is true that the higher stress is at the corner element, but why this happend? Is it I need to redesign the corner?

    The problem of FEA analysis with P-Adaptive method

    Dear respected Engineer, I have found something strange about the P-method in cosmoswork professional. ( but may be I have wrong setting) I found that when I increase the P-Adaptive method, the polynomial I use 3, then 4, loop 3. the maximum stress in analysis become higher and higher. Why...

    About the Pad Eye Design at Corner Post(hoolow beam)

    Dear respected Engineer, I have to design four pad eye at the container design. However, I found that if directly mount/ weld the Padeye at the corner post, there will cause the hollow beam to deform. How to design the padeye at corner post? The container has to pass the test at 35tonnes...

    Question about FEA simulation

    actually I use CosmosWork professional. When I simulate with the material under cosmoswork, the simulation will directly analysis with the yield strength of 230MPa. The result I get the Von mises result is about 200MPa. I found that if I compare with allowable stress Sy = 0.67 x 230 =...

    Question about FEA simulation

    Dear all respected Engineer, I have a question about FEA simulation. During the FEA simulation, I want to analysis a hollow beam with Astm A500 gr A. the yield strength is 230 Mpa. Do I have to use Allowable strenght = 0.67 x yield strength ? or just compare the simulation result to the...
