提出了一种分析平面弹性问题的弱形式求积元方法。建立了平面弹性力学问题的变分形式,并引入了泛函导数的微分求积模拟。通过对几个典型的平面弹性问题的研究,验证了该方法的有效性。结果表明,该方法具有较高的效率和广阔的应用前景。它被应用于分析几乎不可压缩的材料,并显示出对体积锁定的健壮性。讨论了与其他数值方法,特别是p型有限元方法的异同点和优缺点。
A weak form quadrature element method is proposed and applied to analysis of plane elasticity problems. A variational formulation of plane elasticity problems is established and the differential quadrature analog of the derivatives in the functional is introduced. Several typical plane elasticity problems are studied to verify the proposed method. Results show that the method is highly efficient and promising. It is applied to the analysis of nearly incompressible materials and shown to be robust against volumetric locking. Similarities and dissimilarities, advantages and disadvantages as compared with other numerical methods, typically the p-version finite element method are discussed.
