| 摘 要： | 我们基于条件变分问题的理论,建立了一种新型有限元力法,克服了应力函数予先满足静力条件的困难,并能同时给出问题的应力函数和位移函数值,为有限元力法在工程结构中的应用提供了可行的数学离散模型,使力法可以得到更广泛的应用。

| Abstract: | Based on the conditional varational problem,we have pre- sented a new finite element force method that the stress functions doesn't necessarily meet with the equilibrium condition and boundary condition of given forces in advance.At the same time,the stress and displecement function values are obtained to solve structure engineering problems by above method.Therefore,we think that the finite element force method can be applied to engneering struture extensively. |
