A Modified Multi Time Step Integration for Dynamic Analysis
In this paper new implicit higher order accuracy (N-IHOA) time integration based on assumption of constant time step is presented for dynamic analysis. This method belongs to the category of the multi time step integrations. Here, current displacement and velocity are assumed to be functions of the velocities and accelerations of several previous time steps, respectively. This definition causes...
متن کاملAnalysis and Nonlinear Control of Implicit Discrete-time Dynamic Systems
This contribution is concerned with the observability and accessibility analysis of implicit discrete-time dynamic systems. The presented approach is motivated by a geometric representation of discrete-time systems and the crucial observation that the Lie group investigations known for implicit continuoustime dynamic systems is also appropriate in the discrete-time scenario. The obtained formal...
متن کاملOn a composite implicit time integration procedure for nonlinear dynamics
Transient analysis of nonlinear problems in structural and solid mechanics is mainly carried out using direct time integration of the equations of motion. For reliable solutions, a stable and efficient integration algorithm is desirable. Methods that are unconditionally stable in linear analyses appear to be a natural choice for use in nonlinear analyses, but unfortunately may not remain stable...
متن کاملSensitivity analysis for generalized nonlinear implicit quasi-variational inclusions
In this paper, by using the concept of the resolvent operator, we study the behavior and sensitivity analysis of the solution set for a new class of parametric generalized nonlinear implicit quasi-variational inclusion problem in Lp(p ≥ 2) spaces. The results presented in this paper are new and generalize many known results in this field.
متن کاملThe streamline diffusion method with implicit integration for the multi-dimensional Fermi Pencil Beam equation
We derive error estimates in the appropriate norms, for the streamlinediffusion (SD) finite element methods for steady state, energy dependent,Fermi equation in three space dimensions. These estimates yield optimal convergencerates due to the maximal available regularity of the exact solution.High order SD method together with implicit integration are used. The formulationis strongly consistent...
