TriangleElement

Overview

A triangle element is referred to a 2D element, which only have dimension in two direction. It’s features in an quick overview:

  1. It can act as thin shell, thick shell, plate bending or membrane - see Behaviours section.

DoFs of TriangleElement acting as a Membrane

  1. It can have a cross section - see Cross Section section.

  2. It can modeled as PlaneStress or PlainStrain - see Membrane Formulation section.

  3. It can have a material - see Material section.

  4. Several types of loads are possible to be apply on them - see Applicable Loads section.

  5. It Does have a local coordination system, apart from global coordination system - see Coordination Systems section.

  6. It is possible to find internal force of it - see Internal Force section.
