在不同的磨削深度和砂轮速度下对玻璃板进行单点和多点磨削，以评价单点磨削在模拟多点磨削过程中的损伤渗透和材料去除机理方面的有效性。观察到的单点磨削损伤比多点磨削严重得多。在单点磨削和多点磨削中，垂直载荷(PV)与裂纹深度的关系(C)PV∞c1.2。在玻璃中，残余应力在降低受损棒材剩余强度方面的影响小于之前研究的其他陶瓷，主要是因为大部分不可逆变形区通过粉碎被移除。讨论了用单点磨削模拟多点磨削的优缺点。
Glass plates were damaged by single-point and multipoint grinding at various set depths and wheel speeds to evaluate the usefulness of single-point grinding to simulate the mechanisms of damage penetration and material removal during multipoint grinding. The observed damage was much more severe in single-point than in multipoint grinding. In both single-point and multipoint grinding, the vertical load (Pv) dependence of the crack depth (c) Pv∞c1.2. In glass, the effect of the residual stresses in reducing the remaining strengths of the damaged bars was less than that observed for other ceramics previously investigated, mainly because much of the irreversibly deformed zone was removed by crushing. The advantages and disadvantages of using single-point grinding to simulate multipoint grinding are discussed.
