One of the core technologies in lightweight structures is optimal design laminated composite stiffened panels. The increasing tailoring potential new materials added to simultaneous optimization various regions, leading spaces that are vast and non-convex. In order find an using limited information, this paper proposes a workflow consisting experiments, metamodeling phases. A machine learning s...

A micro-meso-macro analysis framework based on the multi-scale method was employed to analyse mechanical behaviour of marine GFRP stiffened panels. The study aims establish a procedure for assessing impact material composition and weave ultimate strength assessment an essential step in design process, investigation construction materials has great benefit lightweight composite structures. micro...

Abstract Typical thin‐walled structures are found in applications like aircraft, spacecraft and marine vessels. For this type of structure, stability behaviour is crucial. The better understood, the full lightweight potential can be exploited. composite especially, new fast analysis tools for preliminary design required to address issue. Therefore, local postbuckling omega‐stringer‐stiffened pa...

The behavior of impact damaged composite laminates under cyclic load is crucial to achieve a damage tolerant design structures. A sufficient residual strength has be ensured throughout the entire structural service life. In this study, set 27 impacted coupon specimens subjected quasi-static and compression load. After long intervals without detectable growth, fail through sudden lateral propaga...

We have recently proposed a new concept for deployable reflectors consisting of a thin parabolic carbon-fibre-reinforced-plastic (CFRP) shell stiffened along the edge by an elastically collapsible stiffener. Here we show that a stiffener accounting for less than 10% of the total mass of the reflector increases the stiffness of the softest deformation mode of the deployed reflector by 48 times, ...
