چکیده انگلیسی


• A new quadrilateral element based on the strain approach named SBQE is developed.
• Both linear and nonlinear behaviors of this developed element are investigated.
• This new element is found to be insensitive to distorted mesh.
• Results obtained using this element show its good performances in both analyses.

Based on the strain approach, a new simple and efficient four-node quadrilateral membrane finite element with drilling rotation is developed. It can be used for the elastic and elastoplastic analysis. The displacements field of this element is based on the assumed functions for the various components of strain which satisfy the compatibility equation and it is developed in some way to improve the element performance in the distorted configurations. This finite element has the three degrees of freedom at each of the four nodes (the two translations and the in-plane rotation) and the displacement functions of the developed element satisfy the exact representation of the rigid body modes. Numerical results show that the proposed strain based element exhibits an excellent behavior for both regular and distorted mesh over a set of problems in both analyses.
