COMPUTER PROGRAM BASED ON FINITE ELEMENT METHOD FOR STATIC ANALYSIS OF PLANAR STRUCTURES OF ARTICULATED WOODEN BARS

摘要

Today modern design must meet several requirements related in particular to be determined by the precision of solutions for various types of structures. A major task is to determine the behavior of mechanical structures or structural elements in effect of external actions. By applying the finite element method, physical systems governed by partial differential equations with having an infinite number of degrees of freedom are reduced to discrete physical systems with a finite number of degrees of freedom governed by algebraic equations. Specifically, the essential question is: what is the answer structure when subjected to external actions (variations of strength, temperature, etc.). Program designed by the authors using the finite element tool engineer put in hand work necessary to optimize the design, with positive effects on the complete analysis of stress and tensions in planar structures of articulated bars.
