泡沫铝力学性能的研究及有限元模拟

摘要

首先对基体材料、特征参数以及应变率等影响泡沫金属力学性能的因素进行了分析叙述,认为无论何种参数都对泡沫铝的力学性能构成一定的影响,各参数影响程度与胞孔结构有关.然后综述了多孔材料模型以及准静态和动态泡沫铝力学性能有限元模拟的研究进展,最后总结了当前的研究结果并提出自己的观点.%The main factors affect mechanical property of the aluminum foams, such as the matrix material,characteristic parameters, strain rate and so on. All parameters would effect on property of the aluminum foams, and the degree of influence is associated with the structure of the cell. The current research results are summarized and own overview is put forward.
