【 摘 要 】

Article shows general principles of elastic plastic continuum mechanics, solid body dynamics and time integration methods. The methods for finite element modeling of steel structure details with high strength bolts and their computation using time domain integration under cyclic loading are considered with due regard to various types of nonlinearities and strain rate effects. Comparison of nonlinear static and nonlinear dynamic dynamics methods that implement explicit and implicit time integration methods of dynamic equilibrium equations is made.
