During the last few decades, industries such as aerospace and wind energy (among others) have been remarkably influenced by the introduction of high-performance composites. One challenge, however, for modeling and designing composites is the lack of computational efficiency of accurate high-fidelity models. For design purposes, using...

Lugs are a specific type of joint with a semi-circular geometry around the pinhole utilized in the aerospace field. Its distinct geometry and ability to carry loads in its plane make it a very common choice for design engineers. Although this type of joint is widely used, there are no analytical equations that can predict the stresses around the...

An analytical model for the onset and growth of delaminations induced by matrix cracks under static loading is proposed. The model introduces four distinct configurations of delaminations originating from crack tips, which are applicable to cross-ply and general symmetrical laminates subjected to tension or tension + shear.<br/><br/>The...

In recent years, the wind energy industry shows more and more interest in composite materials manufactured with a new process called pultrusion. The advantage of pultruded composite plates includes high fiber volume fraction, low price and simplified blade manufacturing. However, pultruded plates are fully cured and crosslinking is absent at...

Ceramic matrix composites (CMCs) are advanced materials that consist of a ceramic matrix reinforced with a high-strength, high-stiffness material, such as carbon fibers. They offer excellent thermal and chemical stability while exhibiting low weight and exceptional mechanical properties. A novel CMC material is the C/C-SiC produced with 2/2...

Acousto-ultrasonic composite transducers (AUCT), which are made of piezoceramic materials embedded in a reinforced polymeric matrix, are promising for the health monitoring of composite structures. However, when they are integrated into highly loaded thermoplastic composite structures, ensuring proper joining properties is a challenge. The...

In recent decades, fibre-reinforced polymer composite structures have seen increased aerospace applications. A typical composite structural element widely used in primary load-bearing aircraft components is the T-joint, which is formed when two orthogonal laminates are joined in a T-shaped arrangement to enable out-of-plane load transfer. Under...

Magnetic Soft (shape memory) Materials (MSM for short) are a form of shape memory hybrid in which the shape change is initiated by magnetic particles embedded in an elastomer matrix. When an external magnetic field is applied, these magnetized particles will align themselves to this magnetic field, straining the elastomer in a specific shape....

Composite structures are used more frequently in newly designed aircrafts. This results in new difficulties compared to conventional metals during operational life. Especially, the material properties of two different materials can cause side effects, which are unwanted in a structure, for example thermal stresses. Many reports have been written...

The continuous homogeneous rail constraint of embedded rail system (ERS) is realized by the encapsulation of rails with the elastic poured compound (EPC) which is a composite material. Previous treatment of EPC as linear elastic material was insufficient in the failure analysis of ERS. In this work, a hyperelastic model is developed to...

A common choice for multiscale modeling of the mechanical response of composites is to use periodic boundary conditions (PBCs) on square and cubical representative volume elements (RVEs). However, when strain localization occurs in the micromodel, these PBCs are unable to reproduce the transverse isotropy of composite materials with a random...

The design of composite products for a circular economy is challenging. Materials such as glass-fibre-reinforced plastics have long product lifetimes but are hard to recycle. For the effective reuse and recycling of products, parts, and materials, recovery strategies must be selected and implemented in the product design stage. This extends the...
