hi,

am new to mechanica am using integrated mode,

pls tell me for what kind of products i should choose beam element,for
what kind of products i should choose shell element and solid element

hope i conveyed my message clearly.

pls help

Beam elements apply for 1-D models, like rods truss-bridges beams...the longest dimension is 10 times or above the others.


Shell elements apply for 2-D modelslike a plate under compression, a pressure vessel...shells are best suited for models where the wall thickness is smaller compared to the overall size (l/t>10), and u have to make sure that the model can be compressed to a mid-surface for idealization.
