Grain size Al sheet made by T3 2024(Size effect of Al sheet)

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.

membrane strain energy for circular plate

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.

Yield line theory application to a edge fixed disk by central load

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.

How to represent a "bird" in ABAQUS

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.




Best regards
