sap5是线弹性结构静动力分析有限元程序。
该程序是美国加利福尼亚大学伯克利分校土木工程教授WILSON和他的博士研究生BATHE等编制。1979.5～1979.7美籍华人学者卞学鐄、张之勇应我国五机部的邀请，在北京工业学院举办有限元学习班，并赠送了该程序。沈阳鼓风机厂、北京汽车制造厂、杭州汽轮机厂、西安六三一研究所、五机部计算中心、二机部遵义计算站、西安红旗机械厂等单位先后进行移植。1980年后陆续调试完毕，投入正常使用。同时对有些工科大学学生进行为期50学时的授课。(SAP5 is a static and dynamic finite element program for linear elastic structures.
The program was compiled by WILSON, a professor of civil engineering at the University of California, Berkeley, and his doctoral student, BATHE. From May 1979 to July 1979, Chinese-American scholars Bian Xuetao and Zhang Zhiyong, at the invitation of the Five Machinery Departments of China, held a finite element course at the Beijing Institute of Technology and presented the program. Shenyang Blower Plant, Beijing Automobile Manufacturing Plant, Hangzhou Steam Turbine Plant, Xi'an 631 Research Institute, Five Machinery Department Computing Center, Second Machinery Department Zunyi Computing Station, Xi'an Red Flag Machinery Factory and other units have been transplanted. After commissioning in 1980, it was put into operation normally. At the same time, some engineering university students teach for 50 hours.)
