The corner element is considered in torsion of a square cross section bar. Understanding the corner element has a pedagogic role in mechanics of materials and elasticity and is also helpful in providing physical insight for generalized continuum theories such as Cosserat elasticity. Analysis of the corner element reveals the slope of the warp curve at the corner in a classical solid and approximates the slope of the warp curve in a Cosserat solid.

经典弹性和 Cosserat 弹性中的角元

在方形横截面钢筋的扭转中考虑角元素。理解角元素在材料力学和弹性力学中具有教学作用，也有助于为广义连续统理论（如 Cosserat 弹性）提供物理洞察力。对角元素的分析揭示了经典实体中拐角处的翘曲曲线的斜率，并近似于 Cosserat 实体中的翘曲曲线的斜率。
