A theoretical solution for Impact response of FML(Fibre-metal lamiantes) is available:

Dear all,

Can anybody give me some papers on the grain size T3 2024?

I know it should be 10-100 μm or so. But I want to get a more precise data and cite it in my journal paper.

All suggestion or papers are welcome. Thanks.

Dear All,

I am presently deducting formula for a metallic circular plate with large deflection. Can anybody help me how to dedcut the  membrane strain energy of a circular plate?

All information on reference or textbook are all welcome.

Thanks.

Dear all,

   I am trying to apply the Yield line theory to analyze the fracture of a disk by central load, F.

   Do anybody know the yield line on the disk? I searched some books to find most references focus on rectangular plate rather than disk.

   All suggestions are welcome. Thanks.

Dear all,

   I will model a bird to impact a shell at high velocity by ABAQUS.  I decide to model the "bird" by ALE mesh and referred by EOS equation.

   However, most simulation works are done by LS-Dyna. Do anyone know how to determine the parameters in ABAQUS for the "bird" in EOS equation?

   All suggestions are welcome.

   Thanks.

Jason,
