The importance of constraint relief caused by rubber cavitation in the toughening of epoxy
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1993-12)
Many rubber-toughened epoxies are thought to derive the bulk of their toughness through the processes of rubber cavitation and plastic shear-yielding in the epoxy matrix. Constraint relief has been considered to be a key ...
Fracture behavior of shear key structures with a softening process zone
(Kluwer Academic Publishers; Springer Science+Business Media, 1993-02)
The objective of this paper is to investigate the fracture behavior of short fiber reinforced ceramic structures by means of the fracture mechanics approach. In this paper, structural stability in relation to crack growth ...
Ductility and toughenability study of epoxy resins under multiaxial stress states
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-07)
The local strains in unmodified and rubber-modified epoxies under multiaxial stress states were examined. Matrix ductility was varied by using epoxide resins of different epoxide monomer molecular weights. The stress state ...

A simplified micromechanical model of compressive strength of fiber-reinforced cementitious composites
(Elsevier, 1992)
A micromechanical model is constructed for the compressive strength of fiber-reinforced cementitious composites (FRCs). This model is based on the classical models of compressive failure of brittle soilds in which sliding ...

Short Fiber Reinforced Thermoplastics: Prediction of Stiffness in Injection Molded PS-PPO Blends
(Sage Publications, 1991)
The prediction of stiffness in short fiber reinforced thermoplastics is stud ied as a function of fiber length using injection molded blends of PS and PPO. The theoret ical models for predicting composite stiffness are ...
Effect of cyclic stress on enthalpy relaxation in polycarbonate
(John Wiley & Sons, Inc., 1992-03-15)
Possible effects of cyclic stress on physical aging in polycarbonate were investigated using differential scanning calorimetry (DSC) measurements. When the enthalpy overshoot by DSC of specimens of different previous ...
