August 2001

Outline
I. Overview of Nonlinear Problems.
Sources of nonlinearities in structural problems: material, geometry, forces, boundary conditions. General
features of nonlinear response: equilibrium trajectories, path dependencies, critical points.
II. Formulation of Geometrically Nonlinear Finite Elements.
Residual and incremental forms. Finite element Total Lagrangian and corotational formulations. FEM
nonlinear equilibrium equations: initial stress, tangent and secant stiffness, geometric stiffness.
III. Solution of Nonlinear Equations
Classification of solution methods. Increment control techniques. Augmented equation methods. Incremental
and pseudo-force methods. Newton methods. Secant (quasi-Newton) methods. Acceleration
and line search. Dynamic relaxation. Determination and traversal of critical points.
IV. Computer implementation of nonlinear analysis (concurrent with II and III)
Model definition. Element level calculations. Equation assembly. Nonlinear equation solver. Residual
evaluation. Post-processing.
IV. Applications to Structural Stability.
Linearized prebuckling. Nonlinear stability analysis. Imperfection sensitivity.
V. Nonconservative Problems
Follower loads. Load stiffness. Overview of dynamic instability phenomena: divergence, flutter.

这个链接好像不能用了！ 22# 继往开来

zhangxd00 发表于 2010-4-6 21:59:23

给点信息，书名，作者啥的提供一下。
不然费了半天劲下了一看没用，那多窝火

非常感谢，非常好的资料啊

fengxiang84 发表于 2010-4-25 11:42:45

谢谢 先看看

refeihc 发表于 2010-4-25 17:44:36

以后再慢慢学习

zgj-chaoyue 发表于 2010-4-25 23:07:42

能不能介绍下啊？也不能这样干发啊？不知道有没有用。:)
