Many of the carbon and natural fibres used in composite reinforcement have a non-circular cross section. Recently non-circular, or flat, section glass fibre products become commercially available. This paper explores potential effects that such shapes may on micromechanics stress transfer at fibre–matrix interface resulting changes strength performance. Analytical modelling is to show how criti...

One of the biggest problems facing use carbon nanotubes in reinforced composites is agglomeration within matrix phase. This phenomenon—caused by Van der Waals forces—leads to dispersion and weakens properties composites. research presents a multi-stage homogenization approach used investigate influence aspect ratio, volume fraction, nanofillers on effective mechanical polymer biocomposite conta...

The use of composite materials for structures subjected to impacts requires a deep understanding about the dynamic behaviour material. To this end, physically-based computational micromechanics simulation tool has been developed predict failure initiation in ply over wide range strain rates. framework incorporates constitutive models fibre, matrix and fibre–matrix interface, which are partly ca...

A review of modeling techniques for predicting the mechanical behavior of polymer nanocomposites is presented. A detailed discussion of Computational Chemistry and Computational Mechanics modeling techniques is given. The specific molecular-based and continuumbased modeling approaches are described in terms of assumptions and theory. The approaches discussed are Ab initio simulations, Molecular...

This paper presents the development and performance assessment of a novel ultra-lightweight high ductility cement composite (ULHDCC) incorporated with fly ash cenospheres, rubber powders low fiber content 0.7%. To address brittle nature such composite, this utilized surface treated polyethylene (PE) fibers to improve behavior, used replacing part cenospheres reduce matrix fracture toughness ach...

A new multiscale micromechanical approach is developed for the prediction of the behavior of fiber reinforced composites in presence of fiber clustering. The developed method is based on a coupled twoscale implementation of the High-Fidelity Generalized Method of Cells theory, wherein both the local and global scales are represented using this micromechanical method. Concentration tensors and e...
