残余应力对钢压杆稳定承载力影响的讨论

Discussion on The Influence of Residual Stress on The Stability Bearing Capacity of Steel Bar

影响钢压杆稳定承载力的关键因素是力学缺陷和几何缺陷,在教学中解释力学缺陷即残余应力影响钢压杆稳定承载力这一环节,学生难于接受,采用创新的教学方法,将抽象理论通过简单推导,利用图、表等可视化的媒介展现给学生,加深学生理解,提高教学效果。

The key factors affecting the stable bearing capacity of steel bar are mechanical defects and geometric defects. It is difficult for students to accept the link of explaining the mechanical defects in teaching, i.e. residual stress affecting the stable bearing capacity of steel bar. In this paper, innovative teaching methods are adopted,which the abstract theory is simply deduced and presented to students through visual media such as graphs and tables.These measures have played a role in deepening students′understanding and improving teaching effect.
