Abstract
A stepped methodology for the evaluation, with limited computational effort critical buckling load factor which produces the instability of the walls of double-T sections is proposed in this work. For this purpose, each wall of the cross-section studied in a local level as a thin [...]
Abstract
The objective of this monograph is to apply the computation methods for critical points to more complex mechanical problems involving inequality constraints. Prior to this extension to a new class of problems appropriate methods among the existing ones for the critical point detection [...]
Abstract
In this contribution, a new form of semianalytical results related to inertial objects that are traversing homogeneous infinite structures, introduced in previous author's work, is used to analyze one-, twoand three-layer models of the railway track. The aim of these analyses is determination [...]Abstract
Simulation problems involving non-linear materials imply in numerous cases divergence of the implicit method which use return mapping algorithms for modelling of the nonlinear response. A switching implicit-explicit numerical technique in the context of Finite Element Methods is presented [...]
