Nowadays lightweight and higher performances place increasing importance to design quality, and both become the critical issues confronted in engineering field. Take transportation industry as an example, there have been a broad range of studies reported on thin-walled structures,in which the plastic deformation is commonly used to absorb majority of kinetic energy when crash occurs. As a class of effective structural components, the corrugated panels have been widely used in engineering practice for its lightweight and high strength-to-weight ratio. For this reason, such structures are gaining increasing attention aiming to make it more crashworthy.You can see a figure at below about experimental work
Sandwich panel is modeled as three dimensional shell part with AL2024 as material. Dynamic explicit is appropriate for this analysis. During the analysis the upper rigid plate by moving causes a huge plastic deformation inside the sandwich plate specifically on the core section. You can see some figures of this simulation at below.
