与经典弹性力学相比，Cosserat弹性力学中的方截面杆在扭转时的横截面翘曲减小。翘曲实验观察到大大减少，由约四个因素相比，经典的弹性，在开孔聚合物泡沫，Cosserat弹性常数先前确定。泡沫中观察到的翘曲与基于Cosserat弹性的预测一致。因此，与经典弹性相比，泡沫中的应变集中减少。
Warp of cross sections of square section bars in torsion is reduced in Cosserat elasticity in comparison with classical elasticity. Warp is observed experimentally to be substantially reduced, by about a factor of four compared with classical elasticity, in an open-cell polymer foam for which Cosserat elastic constants were previously determined. The observed warp in the foam is consistent with a prediction based on Cosserat elasticity. Concentration of strain in the foam is therefore reduced in comparison with classical elasticity.
