Structural analysis – Tdyn RamSeries

BASIC STATIC 3D FEM ANALYSIS
Features a 3D Finite Element (FEM) analysis package in linear static conditions. The advanced FEM technology provides rich functionality, allowing combination of beams, shells and solid elements, advanced constraints definition, disconnection of degrees of freedom (ball/ cylindrical-joint), flexible load definition and combination of load cases.

DYNAMIC ANALYSIS
Includes the latest technology for dynamic analysis of structures, featuring different types of dynamic analyses including step-by-step direct integration, modal/vibration and seismic analysis. The module supports static and dynamic load definition, either by analytical functions or data tables, response spectra and several modes of damping definition.

COMPOSITE MATERIALS
Offers advanced utilities to analyze structures made of beam or shell laminated composites, and provides an intuitive interface to define materials, laminate sequences and ply direction, based on geometric lines orientations or local or global frames of reference. RamSeries can manage a global database of predefined sequences and materials to be shared by a design team.

NON-LINEAR ANALYSIS
Features different material constitutive laws in order to analyze complex model behavior. Among others, it includes J2 plasticity for shell elements, including Isotropic or Kinematic hardening. The geometry can be analyzed assuming large displacements for all the element types. Contact-impact algorithms use the most advanced element to element approach. Contacts can be modelled either as frictionless or sticking.

COUPLING WITH Tdyn CFD+HT AND Tdyn SeaFEM
Offers seamless communication with Tdyn CFD+HT modules for thermo-mechanical and coupled fluid-structure analyses (aero/hydro-elasticity). Furthermore, this module features one-way and two-way interaction links to the Tdyn’s seakeeping package Tdyn SeaFEM, allowing to perform the most advanced wave-structure interaction studies.
