The research on strength and fracture of materials has been made on various size scales with solid physics, material science, continuum mechanics and so on. It is, however, pointed out that the recent demand for developing new materials as well as for using materials under severe conditions requires an unification of the microscopic and macroscopic research. To do this, the researchers who have studied the material behaviors related to strength and fracture need to gather, discuss and exchange ideas on the Meso-Mechanical Aspects of Material Strength and Fracture. The international research group was formed with this objective. During the research period1 three meetings were held. First meeting took place at Tokyo Institute of Technology in 1996, followed by the meeting at California Institute of Technology in January 1998 and the last meeting was at Ecole Polytechnique in France, 1998. Through these meeting and cooperative research, a variety of ideas for achieving increased understanding of the behaviors related to strength and fracture.

从固体物理学、材料学、连续介质力学等方面对材料的强度和断裂进行了不同尺度的研究。然而，有人指出，近年来开发新材料以及在苛刻条件下使用材料的需求要求微观和宏观研究的统一。为此，研究材料强度和断裂相关行为的研究人员需要聚集在一起，就材料强度和断裂的细观力学方面进行讨论和交流。为此目的成立了国际研究小组。在研究期间举行了三次会议。第一次会议于1996年在东京工业大学举行，随后于1998年1月在加州理工学院举行，最后一次会议于1998年在法国综合理工学院举行。通过这些会议和合作研究，实现了对强度和断裂相关行为的多种理解。
