A floating connector element formulation for multi-level modelling of composite structures

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Multi-level μ-Finite Element Analysis for Human Bone Structures

Impairment of the musculoskeletal system, e.g. osteoporosis or osteoarthrosis, are among the most frequent diseases in the industrialized world. Osteoporosis is a disease characterized by low bone mass and deterioration of bone microarchitecture. It leads to increased bone fragility and risk of fracture, particularly of the hip, spine and wrist. Worldwide, lifetime risk for osteoporotic fractur...

A micromechanics-enhanced finite element formulation for modelling heterogeneous materials

In the analysis of composite materials with heterogeneous microstructures, full resolution of the heterogeneities using classical numerical approaches can be computationally prohibitive. This paper presents a micromechanics-enhanced finite element formulation that accurately captures the mechanical behaviour of heterogeneous materials in a computationally efficient manner. The strategy exploits...

A Multi-Level Decision Fusion Strategy for Condition Based Maintenance of Composite Structures

In this work, a multi-level decision fusion strategy is proposed which weighs the Value of Information (VoI) against the intended functions of a Structural Health Monitoring (SHM) system. This paper presents a multi-level approach for three different maintenance strategies in which the performance of the SHM systems is evaluated against its intended functions. Level 1 diagnosis results in damag...
