Webmations is to use the discrete Kirchhoff theory. This approach can directly be employed to establish simple shell elements and our DKT (discrete Kirchhoff trian- gular) element is one of that kind[5-7]. l~oth elements can be employed for large displace- ment and elastic-plastic analysis, but there are distinct Web10 aug. 2024 · How should I set up the software to distinguish these two types of research? The shell and plate interfaces use thick plate (Mindlin) theory. When you decrease the thickness, the solution converges to what you will get using thin plate (Kirchhoff) theory. You cannot explicitly force thin plate theory for a thick shell. intcountとは https://cancerexercisewellness.org
