有限元法是工程领域中应用最广泛的一种数值计算方法,从力学分析问题的角度来看,已在弹性静力学问题、动力学问题、弹塑性与接触力学、蠕变、疲劳与断裂力学、流体力学和热力学等领域得到广泛的应用。泡沫铝材料的力学性能主要包括压缩性能、拉伸性能、弯曲性能、冲击性能、吸能性等。本文详细叙述了有限元模拟泡沫铝压缩性能的现状及成果,简单介绍了模拟泡沫铝弯曲性能和吸能性的现状和成果,最后针对现状提出了自己的观点和看法。
The finite element numerical method is widely used in engineering field.h has got wide application in mechanics analysis,such as Elastic statics, Dynamics,Elasto-plastic contact mechanics,Creep, Fatigue and fracture mechanies, Fluid mechanics and thermodynamics, etc.The mechanical properties of aluminum foams mainly include compression property, tensile property, bending property e,impact resistance and energy absorption property,etc.This paper introduces the status and achievements of finite element method applied in the compression and bending performance of aluminium foam and present some views and opinions aiming at the present situation.
