This research project experimentally and numerically investigates the growth and coalescence of pre-existing voids for a wide range of stress states in a ductile matrix with a special focus on shear dominated loading conditions and presents quantitative ki ...
Effects of non-uniform strains on tensile fracture of fiber-reinforced ceramic–matrix composites have not been satisfactorily explained by existing mechanics-based models. In this paper, we use an exact model of fiber fragmentation under global load sharin ...
Carbon matrix carbon nanotube (CNT) composites have a broad range of applications because of the exceptional mechanical properties of both matrix and fibers. Since interfacial sliding plays a key role in determining the strength and toughness of ceramic co ...
We study mechanical reinforcement in a widely used epoxy matrix with the addition of graphene nanoplatelets (GnPs) and various mixture ratios of carbon nanotubes (CNTs) with GnPs. Two different dimensions of GnPs were used with flake sizes of 5 mu m and 25 ...
Being good structural replacement for other conventional material, the pultruded glass fiber reinforced polymer (GFRP) profiles are being increasingly used in civil engineering structures. The connection between components is considered the most suspect ar ...
The behaviour of brittle matrix fibre reinforced-composites is dependent of the properties of its constituents (fibre, matrix and fibre-matrix interface) and is affected by the mechanical and environmental loads. The fracture of a unidirectional composite ...
It is well known that moisture absorption impairs the mechanical and physical properties of polymers. Conventionally, the material's hygric strains are described as the product of a constant coefficient of moisture expansion (CME) and moisture concentratio ...
A partially embedded long fibre-Bragg grating (FBG) into an epoxy cylindrical specimen is used to monitor the strain distribution evolution along its axis when subjected to subsequent cycles of thermal ageing at 70 and 110 degrees C. Assuming a total volum ...
The present work is aimed at studying the effect of solidification rate on reinforcement clustering in particle reinforced metal matrix composites (PMMCs) through numerical simulations and experimental studies. A macrotransport-solidification kinetics (MTS ...
Over the past decades the use of composite materials has enormously increased, especially in the aeronautical, automotive, and energy production industries. These materials allow to build lighter and larger structures which are more efficient. However, by ...
