本文提出了利用基于一系列线弹性有限元解来获得弹塑性材料结构的极限承载能力的试验误差法，并将它与切线法和割线法进行了比较和讨论。

Nonlinear equations of the iterative solution, including : simple iterative method, Newton, secant, to the Newton law.

非线性方程组的迭代解法，包括：简单迭代法、Newton法、割线法、拟Newton法等。

The major implementations of the developed model include: Pseudo-spectral and finite-difference schemes are employed to approximate the spatial-differential operators in the horizontal and vertical directions, respectively. A second-order Runge-Kutta method is adopted to integrate in time for the velocity field and the free-surface elevation. The solenoidal condition of the velocity field is satisfied by solving the transformed pressure Poisson equation. A modified secant method is used to accelerate the iterative solution of the non-separable Poisson equation.

模式的主要数值方法包括：分别以拟频谱法以及二阶有限差分法近似控制方程与边界条件中的水平与垂直导数；以二阶Runge-Kutta法进行非稳态的自由液面位移与流场速度的时间积分；利用改良式割线叠代法求解计算区间中不可分离的压力Poisson方程式，以满足不可压缩流条件。

And simulation results also prove secant and discrete Newton"s method based adaptative methods application to memoryless PD have a certain role in modifying PD"s parameters, but do not meet the requirement.

进一步，仿真证明了无记忆预失真中的基于割线法和离散牛顿法的自适应方法对记忆预失真器具有一定的调节作用，但是效果不理想。

The result makes clear: EThe tensile strength of TFE film increases somewhat along with the addition of drawing speed, and rupture outspread rate reduces;ETFE to succumb filmily somewhat along with the addition of drawing speed the addition that intensity follows drawing rate and increase somewhat, but the 2nd succumb intensity increases not big;ETFE to succumb filmily meet an emergency follows drawing rate increase somewhat, the 2nd succumb the amount of tangent and stretch model that meet an emergency reduces;ETFE film somewhat and model of the 2nd flexibility measure those who follow drawing rate to increase show downtrend, quantity of secant flexibility model and quantity of the 3rd stretch model do not have apparent change.

结果表明：ETFE薄膜的抗拉强度随拉伸速度的增加略有增加，而断裂延伸率随拉伸速度的增加略有减小；ETFE薄膜的屈服强度随拉伸速度的增加而有所增加，但第二屈服强度增加不大；ETFE薄膜的屈服应变随拉伸速度的增加略有增加，第二屈服应变则略有减少；ETFE薄膜的切线弹性模量以及第二弹性模量随拉伸速度的增加呈下降趋向，割线弹性模量和第三弹性模量则没有明显的变化。
