摘要: 提出了一种适用于Ｇａｌｅｒｋｉｎ边界元法的高次单元插值方法和半解析半数值的积分方法准高次元法，建立了有关数值模型和将该方法应用于结构弹塑性分析的算法模型．有关算例结果表明，本文建议的方法是切实可行的．Abstract: A two-stage interpolation Galerkin boundary element method called the Quasi-High Order Element Method (QHOEM) is proposed for solving elastoplastic problems. In the initial stage, it uses high order elements to interpolate the coordinates and the variables. For the numerical integration involved, it further uses interpolation to decompose the high order elements into low order elements so that the existing analytical integration formulas can be applied. By doing this, the proposed method yields good adaptab...
