关于极端力学

随着前沿科学和新技术不断发展,工程材料与结构的超常规尺度、密度、硬度、刚度等性能以及在超常规温度、速度、场强和恶劣天气等极端服役环境中的力学响应规律,需要力学提供更为有效的理论和方法. 本报告从极端力学的基本定义和科学内涵出发,结合重大工程问题和大科学问题,从极端性能、极端载荷、学科发展等三个方面系统介绍了极端力学的研究现状,并总结了极端力学的特点及其对力学理论、计算方法和实验技术的挑战,最后对极端力学未来的发展进行了展望. 

EXTREME MECHANICS 1)

With the continuous development of cutting-edge science and new technologies, the studies on the ultra-conventional scale, density, hardness, stiffness and other properties of engineering materials and structures, as well as their mechanical behavior in extreme environments, such as ultra-conventional temperature, speed, physical and chemical fields, and severe weather, requires more effective theories and methods of mechanics. This presentation starts from the fundamental definition and scientific connotation of extreme mechanics, introduces the research status of extreme mechanics from three aspects: extreme properties, extreme loads, and discipline development, in combination of grand engineering and scientific challenges. The characteristics of extreme mechanics and major challenges in the aspects of mechanical theory, computational methods and experimental techniques are concluded. Prospects for the future development of extreme mechanics are proposed.
