Impact
In recent years, impact accidents caused by various reasons have led to significant casualties and property losses. The impact resistance of building structures has become a major challenge in the fields of civil and mechanical engineering. Impact loads are strong dynamic loads characterized by a high loading rate, short acting time, and significant destructiveness, which can be fatal to structural integrity.
Numerical simulation based on the finite element method provides an effective way to analyze the dynamic performance of different specimens under various working conditions. Among the available tools, the LS-DYNA program is currently the most widely used finite element analysis software in this field. Many researchers have used this software to simulate the dynamic response of structures under impact loads, achieving significant results.
Impact testing is performed to determine the impact resistance or toughness of materials by calculating the amount of energy absorbed during impact or fracture.
