Computational co-design framework for coreless wound fibre–polymer 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...

Improved Design Scenario for Composite Airframe Structures

European aircraft industry demands for reduced development and operating costs, by 20% and 50% in the short and long term, respectively. Contributions to this aim are provided by the completed project POSICOSS and the running follow-up project COCOMAT, both supported by the European Commission. As an important contribution to cost reduction a decrease in structural weight can be reached by expl...

Cellulose composite structures – by design

Satellite Conceptual Design Multi-Objective Optimization Using Co Framework

This paper focuses upon the development of an efficient method for conceptual design optimization of a satellite. There are many option for a satellite subsystems that could be choice, as acceptable solution to implement of a space system mission. Every option should be assessment based on the different criteria such as cost, mass, reliability and technology contraint (complexity). In this rese...

Computational plasticity and viscoplasticity for composite materials and structures

A typical aerospace composite component can be modeled on (at least) three different scales: (i) macroscale (structural level), (ii) mesoscale (laminate level), and (iii) microscale (the level of microconstituents). Additional scales can be introduced into the model. For example, the scale of material heterogeneity in each microphase, such as dislocations and grain boundaries, could be consider...
