Solid Edge

The manufacturing process sheet can be output by the design of wooden crates based on Solid Edge. According to the process sheet, the sample crate was produced to obtain and process experimental data of stacking test. By applying inverse method combined with finite element method, the CAE model can be reconstructed quickly. Deflections of the wooden crate were computed by finite element analysis. By comparing deflections to experimental data, elastic modulus of the wooden crate can be adjusted to meet the requirements. The research on elastic modulus will lay the foundation for determining CAE model and structural design optimization of wooden crates.

Plate System

The ultimate compressive strengths of high performance steel (HPS) plate system stiffened longitudinally by closed stiffeners have been investigated by the nonlinear finite element analysis. Both conventional and high performance steels were considered in models following multi-linear strain hardening constitutive relationships. Initial geometric imperfections and residual stresses were also incorporated in the analysis. Numerical results have been compared to compressive strengths from Eurocode 3 EN 1993-1-5 and FHWA-TS-80-205. It has been found that although use of Eurocode 3 EN 1993-1-5 and FHWA-TS-80-205 may lead to highly conservative design strengths when very large column slenderness parameters are encountered
