摘要
利用热力学原理和损伤力学理论对物料的破碎过程进行分析,获得物料破碎过程中的应力方程,并通过大理石循环加载实验,验证物料破碎过程中的应力方程合理性,从而得到应力方程的临界值可作为物料破碎的强度判据.
Based on thermomechanics principle and damage mechanics theory,the stress of material crushing process is analyzed,and the stress equation of material crushing process is obtained.The stress equation is sensible according to the experimental results of marble cyclic loading,and the criterion of material crushing is provided by critical value of the stress equation.
