摘要
以热弹性力学理论为基础,采用偏微分方程组的边值理论和二维奇异积分方程理论,对半刚性路面中基层已产生贯穿厚度的裂缝时的温度应力场进行了研究,得到了裂缝尖端应力强度因子的理论解,并以此对半刚性基层温缩裂缝的扩展机理进行了定量分析。
Based on the thermoelasticity, this paper studies the thermal stress field at the crack tip along the semi rigid base thickness by the boundary value theory of partial differential equations and two dimensional singular intergral equation theory, advances the theoretical solution of stress intensity factor and makes a quantitative analysis on the developing mechanism of thermal crack of the semi rigid roadbase.
