| 摘 要： | 本文将计算力学的边界元法和实验力学的激光散斑法相结合用于求解受力物体的应力应变场。即用实验提供变形物体的真实边界条件,用数值方法进行求解。文中定义了虚边界的概念,并进一步提出了子域杂交法。同单纯数值计算和实验分析相比较,本文提出的方法无需构造力学模型,因而具有简单、可靠的特点,并可以更好地应用于实际问题。

| Abstract: | Stress-strain field of a loaded body is determined by combination of boundry element and speckle method. In other words, solution of deformed body is computed according to real boundry condition obtained experimentally. The concept of fictitious boundry is brought out and hybrid method of subregion is proposed. In compare with pure numerical or pure experimental method, this is simple, more reliable and better in solving practical problems. |
