Is Shell elements are appropriate for stress analysis of assembly?
Hi,
Shell elements are appropriate for stress analysis. Normally based on the dominant dimensions of the geometry the type of element is selected.
Shell elements are used when two of the dimensions are very large in comparison to the third one. Typically for all sheet metal parts, plastic components like instrument panels, etc shell mesh is used.
which quality criteria are essential for terta mesh ?And what should be their value.
Please go through this document http://www.altairuniversity.com/wp-content/uploads/2014/02/elemquality.pdf which describes about the element quality checks for tetra elements and their ideal values.
As I want to perform stress analysis on assembly having both shell and solid parts.What points should I need to keep in mind while performing stress analysis on an assembly having 1d,2d and 3d type elements?
Hi Ank,
Note that the Dofs on shell and solid elements are not same. So if you are connecting shells and solids better you do it with either rigids or use tie contacts.
