Exploring multi-method analysis of composite structures and joints under consideration of uncertainties during engineering and processing

Abstract

EMMA project responds to the M-ERA.NET Call 2020, Topic 1: Modeling for materials engineering and processing. Within this topic and in coherence with the existing and planned developments at the M-ERA Consortium and European industry, the overall objective is to enhance the European competitiveness for the next generation of robust damage tolerant designs and reliable multi-method approach for analysis of composite structures and joints, under consideration of fatigue loadings and uncertainties during engineering and processing. The proposal will address subjects related to constitutive relations discovery, based on physical hypotheses and models of fundamental relations. The proposal focusses on the following domains: Fracture and fatigue phenomena, High performance composites, 3D printing and additive manufacturing. Moreover, this project aligns closely with the expected results: a) Developing new methods and algorithms for simulations of the physics of materials by focusing on the implementation of Peridynamic material and fracture models for thermoplastic composite material. Using this results in classical finite element method to predict damage initiation and evolution at global scale. b) Interaction of numerical simulation and experiments for verification of constitutive models. c) Implementation of Peridynamic models in a Finite Element Analysis Environment for numerical simulation of fatigue damage propagation. d) Dissemination of material database and use cases through papers published on recognized international journals.
