Impact
Simulate the dynamic response of structures under impact loads...
In recent years, impact accidents caused by various reasons have caused a large number of casualties and property losses. The impact resistance of building structures has become a difficult problem in the field of civil and Mechanical engineering. The impact load is a kind of strong dynamic load with high loading rate, short acting time and great destructiveness, which is fatal to the structure damage.
The numerical simulation based on the finite element method provides an effective means to obtain the dynamic performance of different specimens under more working conditions, among them, 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 and have achieved rich 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.
