We developed several computer programs and an experimental technique for mechanical strength evaluation of advanced devices. The computer programs developed in the present research project are a program for fracture mechanics evaluation of interface between anisotropic bimaterial, a program for dislocation evaluation using a constitutive equation including microscopic information of materials such as dislocation density, and a molecular dynamics program for large scale problems. As an experimental technique, we developed systems for measuring strain distribution of small region with the use of images taken by an optical microscope or a scanning laser microscope. We performed mechanical strength studies for electronic devices using the analytical and experimental techniques developed in the present research project.

我们开发了多个计算机程序和一种用于先进设备机械强度评估的实验技术。本研究项目开发的计算机程序是用于各向异性双材料之间界面断裂力学评估的程序、使用包括位错密度等材料微观信息的本构方程进行位错评估的程序以及用于大规模问题的分子动力学程序。作为一项实验技术，我们开发了利用光学显微镜或扫描激光显微镜拍摄的图像来测量小区域应变分布的系统。我们使用本研究项目中开发的分析和实验技术对电子设备进行机械强度研究。
