摘要：
We present a low-order nonconforming mixed element for plane elasticity on rectangular meshes. The 3-dimensional space of rigid body motions is used to approximate the displacement and a 16-dimensional space is used to discretize the space of symmetric tensors. This element may be viewed as the rectangular analogue of the nonconforming Arnold-Winther element and is related to a discrete version of the elasticity differential complex with a nonconforming H2 element related to the rotated Q1 element.
