Download Structural Mechanics Modelling and Analysis of Frames and Trusses By Karl Gunnar Olsson And Ola Dahlblom
Preface
A useful computational model should be simple enough to be easily manageable and, simultaneously, sufficiently complex to provide an adequate accuracy. In recent years, the finite element method has become the dominant method for formulating computational models and conducting analyses.
The FE method is based on expressing forces and deformations as discrete entities in a chosen and representative set of degrees of freedom.
Between the degrees of freedom simple bodies (elements) are placed and together they constitute the structure to be modelled. Each element may describe a unique mode of action and can be given a specific geometry.
In all this, FEM provides opportunities for both accurate analyses of structures with complex geometry and material behaviour, and for quick estimates in early design stages.
