2.1.1. Introduction

RamSeries is a numerical simulation solver for structural analysis, based on the finite element method (FEM). It offers a large set of numerical capabilities that can be used for the analysis of a wide range of structural problems, from linear statics to linear and non-linear transient simulations and modal analysis. It can be used as well to simulate impact, coupled fluid-structure analysis, thermomechanical problems, fatigue assessment of structures and much more. RamSeries includes a full range of 3D structural element models, including beams, cables, shells, membranes and solid elements. It also considers both linear and non-linear material’s constitutive laws including advanced models for laminated composite structures.

This document is intended to provide a brief introduction to some of the basic theoretical aspects underlying the RamSeries solver. To this aim, the fundamentals of structural analysis are presented first together with the basic material constitutive models available in RamSeries. Next, fundamental aspects of the dynamic analysis and the non-linear analysis are also underlined.
