本文叙述了实验教学在材料力学课程中的作用,介绍了一种新的材料力学综合试验。利用微机控制电子万能材料试验机和动态应变数据采集分析仪,对拉伸试件施加拉、压交变载荷并测试其动应力。对测试结果进行了分析、比较,使得学生对交变荷载和动应力测试有了进一步的了解。 This paper describes the role of experimental teaching in the course of material mechanics and introduces a new comprehensive test of mechanics of materials. Using computer controlled electronic universal material testing machine and dynamic strain data acquisition analyzer, tensile and compressive load was applied to tensile specimen and its dynamic stress was tested. The test results were analyzed and compared, enabling students to further understand the alternating load and dynamic stress testing.
