Complex potentials and integral equations for curved crack and curved rigid line problems in plane elasticity

Summary In this paper, a simple layer potential and a double layer potential are suggested to solve the curved crack problem. The complex potentials in the simple layer case are formulated on the distributed dislocation along the curve. Meantime, the complex potentials in the double layer case are formulated on the crack displacement opening distribution. Behaviors of the complex potentials, for example the behaviors of increments of some physical quantities around a large circle, are analyzed in detail. Continuity and discontinuity of some physical quantities in the normal direction of the curve are analyzed, which are key points for formulating the integral equations of the problems. One weaker singular, two singular and one hypersingular integral equations are suggested to solve the problems. The relations between the kernels in different integral equations are addressed. Similarly, a simple layer potential and a double layer potential are suggested to solve the curved rigid line problem. The complex potentials in the simple layer case are formulated on the distributed forces along the curve. Meantime, the complex potentials in the double layer case are formulated on the resultant force function. One weaker singular, two singular and one hypersingular integral equations are suggested to solve the problems. When the resultant forces and moment are applied on the deformable line, the constraint equations are suggested. For more general cases, for example, in the case that the tractions applied on the two crack faces are not same in magnitude and opposite in direction, a singular integral equation is suggested. The equation is obtained by a superposition of two kinds of single layer potentials.

Modeling the effective elastic properties of nanocomposites with circular straight CNT fibers reinforced in the epoxy matrix

In the present study, the consistent effective elastic properties of straight, circular carbon nanotube epoxy composites are derived using the micromechanics theory. The CNT composites are known to provide high stiffness and elastic properties when the shape of the fibers is cylindrical and straight. Accordingly, in the present work, the effective elastic moduli of composite are newly obtained for straight, circular CNTs aligned in the specified direction as well as distributed randomly in the matrix. In this direction, novel analytical expressions are proposed for four cases of fiber property. First, aligned, and straight CNTs are considered with transverse isotropy in fiber coordinates, and the composite properties are also transversely isotropic in global coordinates. The short comings in the earlier developments are effectively addressed by deriving the consistent form of the strain tensor and the stiffness tensor of the CNT nanocomposite. Subsequently, effective relations for composites reinforced with aligned, straight CNTs but fibers isotropic in local coordinates are newly developed under hydrostatic loading. The effect of the unsymmetric Eshelby tensor for cylindrical fibers on the overall properties of the nanocomposite is included by deriving the strain concentration tensors. Next, the random distribution of CNT fibers in the matrix is studied with fibers being transversely isotropic as well as isotropic when CNT nanocomposites are subjected to uniform loading. The corresponding relations for the effective elastic properties are newly derived. The modeling technique is validated with results reported, and the variations in the effective properties for different CNT volume fractions are presented.
