Deformation Characteristics of Composite Structures
The composites provide design flexibility because many of them can be moulded into complex shapes. The carbon fibre-reinforced epoxy composites exhibit excellent fatigue tolerance and high specific strength and stiffness which have led to numerous advanced applications ranging from the military and civil aircraft structures to the consumer products. However, the modelling of the beams undergoin...
متن کاملMechanics of interfacial composite materials.
Recent experiments and simulations have demonstrated that particle-covered fluid/fluid interfaces can exist in stable nonspherical shapes as a result of the steric jamming of the interfacially trapped particles. The jamming confers the interface with solidlike properties. We provide an experimental and theoretical characterization of the mechanical properties of these armored objects, with atte...
متن کاملSuppression of Fracture Failure of Structures by Composite Design Based on Fracture Mechanics
This paper discusses the use of fracture mechanics for the microstructure tailoring of a fiber reinforced Engineered Cementitious Composite (ECC) to achieve extreme tensile ductility at the composite scale. It demonstrates that fracture mechanics applied to control fracture phenomena at the micro and meso material scales can lead to suppression of fracture failure at the macro structural scale....
متن کاملComputational Mechanics of Fatigue and Life Predictions for Composite Materials and Structures
A multiscale fatigue analysis model is developed for brittle composite materials. The mathematical homogenization theory is generalized to account for multiscale damage effects in heterogeneous media and a closed form expression relating nonlocal microphase fields to the overall strains and damage is derived. The evolution of fatigue damage is approximated by the first order initial value probl...
متن کاملRecent Studies on Micro- and Macro- Mechanics of Composite Materials and Structures
During these few years, several different topics about the microand macromechanics of composite materials and structures have been studied in my research group. They include: defects in composite materials and structures; contact problems; buckling, vibration and control of the composite laminated constructions; aeroservoelasticity of composite wing structures; a novel formalism for the bending...
