Abstract: One of the experimental findings on short-fiber reinforced composite materials is that the fiber-ends act as a crack initiator. The effect of the fiber-end crack on the overall stiffness and ...

Abstract: Relaxation of misfit strains at interfaces between two different materials by dislocation punching is studied analytically by focusing on two types of interfaces: planar and nonplanar. As an ...

Abstract: In this paper, the elastic field in an infinite elastic body containing a polyhedral inclusion with uniform eigenstrains is investigated. Exact solutions are obtained for the stress field in ...

Abstract: In this paper the elastic fields in an arbitrary, convex polygon-shaped inclusion with uniform eigenstrains are investigated under the condition of plane strain. Closed-form solutions are obtained ...

Abstract: A formulation to compute the effective thermal expansion coefficients (αc ) of an anisotropic short fiber-reinforced composite and the thermal stress (σ) induced in and around the fiber is ...

Abstract: The stresses induced in and around a coated short-fiber composite are investigated by use of the Boussinesq-Sadowsky stress function. The coated fiber is assumed to consist of two confocal ...

Abstract: This paper examines an important aspect of the hygrothermal effect in fiber composite materials, the deformation induced by matrix shrinkage. The physical problem is simulated by prescribing a ...

Abstract: Four different aligned W-1%ThO2 reinforced Fe-25Cr-8Al-0.5Y matrix fiber reinforced superalloy [FRS] material billets were produced by powder metallurgical processing. Three materials differed only ...

Abstract: This paper examines the effective longitudinal Young’s modulus of composites containing misoriented short fibers. The analysis is based on the Eshelby’s equivalent inclusion method and the average ...
