Finite Strip Method

In this paper, the application of previously the semi energy finite strip method (FSM) for the non-linear post-buckling analysis of rectangular anti-symmetric laminates is extended to include the effects of normal pressure loading in addition to the progressive end-shortening. One of the main advantages of the semi-energy FSM is that it is based on the closed form solution of von Kármán’s compatibility equation. The developed finite strip method is applied to analyze the large deflection behavior of anti-symmetric angle ply composite laminated plates with simply supported boundary conditions at its loaded ends. To validate the results, they are compared with those obtained from finite element method (FEM) of analysis.

This paper presents scope of parallelization in large displacement stability analysis of orthotropic prismatic shells with simply supported boundary conditions along the diaphragm-supported edges. A semi-analytical harmonic coupled finite strip method (HCFSM) is used to solve the large deflection and the post-buckling problems. In the HCFSM formulation the coupling of all series terms highly increases computation time when a large number of series terms is used. Fortunately such computation time increase can be compensated by application of MPI, OpenMP and CUDA approaches to parallelization. This paper shows how these approaches can be applied to HCFSM formulation, and what results can be expected.

Finite Strip Method

In order to calculate internal forces of a structure resulting from heat input, it is necessary to know how thermal conduction in relation to specific material properties and boundary conditions determines the temperature distribution at various points of the structure. The finite strip method (FSM) is very suitable for the analysis of heat and temperature distribution, heating, and thermal conduction in engineering structures. It (FSM) is especially suitable for those structures of rectangular shape and of identical edge conditions.The work presented illustrates several examples for various types of engineering structures utilizing the FSM for the analysis of thermal conduction and heat and temperature distribution, such as, for instance, the welding of several joined elements with linear welds made at a specified speed or as point welds. Types of structures subject to thermal analysis may be bars, shields, square and rectangular plates, steel orthotropic plates, steel and combined girders (steel–concrete), and box girders. The obtained results may be useful in engineering practice for determining actual temperatures and load capacities in individual elements of the construction. Key words: structural engineering, thermal analysis, finite strip method, heating, thermal conduction, temperature, engineering structures.
