摘要
从能量平衡角度对工程材料Ｋｎｏｏｐ硬度的压痕尺寸效应作出新的理论解释．认为在压痕过程中只有一部分荷载功转化为材料发生不可逆体积形变所消耗的能量；
Based on the energy balance consideration, a new theoretical explanation is presented for the indentation size effect of Knoop hardness of engineering materials. It is shown that only part of the work done by applied load has been transformed to the energy to cause the irreversible volume deformation of material during indentation. The extra dissipation of the work done by applied load is the main cause for the decreasing tendency of Knoop hardness with increased indentation size.
