Simulation of Composite Material Damage in ABAQUS

Introduction

FEA Simulation of composite material damage is one of the most important issues in academic research and industrial applications. The damage can be in the wind turbine blades or in impact on a composite plate or composite pressure vessels or in composite pressure hull and so on. According to the modeling done by the micro or macro method, the way of defining the damage completely follows the separate method in ABAQUS.

In this package, which focuses on how the modeling of composite materials is modeled by the macro method while introducing various theories to initiate and progress the damage of these materials and existing constraints based on software capabilities for different elements, teach users to simulate their models in ABAQUS.

Workshop 1

In this simulation, a multilayer composite plate with different orientations with holes with a shell element is placed under the tensile load as a nonlinear function inside the hole. In this simulation, the damage initiation is based on Hashin’s Physics-based phenomenon criterion and progressive damage is gradual on the basis of energy. In the HASHIN criterion failure in fiber and matrix is investigated separately in compression and tension. So, the user nows in which mode failure occurs and  can reinforce his composite

Workshop 2

In this model,  simulation of the composite material damage is performed based on non-physical phenomenon criteria such as Tsai-Hill and Tsai-Wu on a multilayered plate with a continuum element. Note that the simulation method and the necessary points for modeling are completely different from the previous workshop.

Workshop 3

In this simulation, a composite cylinder is hit by a hemisphere. In this dynamic analysis, the composite material damage for initiation and progression is investigated using the Hashin criterion.

Workshop 4

High-speed impact simulation is one of the most widely used applications in industry today. In this simulation, a composite multilayer sheet is impacted and the amount of energy absorbed by the sheet is calculated. The damage criterion of the composite is HASHIN criterion for failure initiation and energy criterion for progressive failure.

Workshop 5

In the last workshop, the composite material damage along with the adhesive damage is examined. This time, the impact is made on a composite plate with continuum elements, which is glued between its layers. After the bullet hits the composite plate, the composite damage and the effect of lamination are both visible at the same time.
