Optimizing fiber orientation in fiber-reinforced materials using efficient upscaling
We present an efficient algorithm to find an optimal fiber orientation in composite materials. Within a two-scale setting fiber orientation is regarded as a function in space on the macrolevel. The optimization problem is formulated within a function space setting which makes the imposition of smoothness requirements straightforward and allows for rather general convex objective functionals. We...
متن کاملThe Effect of Fiber Orientation on the Toughening of Short Fiber-Reinforced Polymers
The effect of fiber orientation on the toughening of polymers by short glass fibers generally below their critical length was investigated using specimens with either well-aligned or randomly oriented fibers. The fibers were aligned by an electric field in a photopolymerizable monomer, which was polymerized while the field was still being applied. These materials were fractured with the aligned...
متن کاملEffects of Fiber Length and Fiber Orientation Distributions on the Tensile Strength of Short-fiber-reinforced Polymers
This paper presents an analytical method considering the effects of fiber length and fiber orientation distributions for predicting the tensile strength (TS) of short-fiber-reinforced polymers (SFRP). Two probability density functions are used for modelling the distributions of fiber length and fiber orientation. The strength of SFRP is derived as a functiolz of fiber length and fiber orientati...
متن کاملNumerical Evaluation of Single Fiber Motion for Short-fiber-reinforced Composite Materials Processing
This paper presents a computational approach for simulating the motion of a single fiber suspended within a viscous fluid. We develop a Finite Element Method (FEM) for modeling the dynamics of a single rigid fiber suspended in a moving fluid. Our approach seeks solutions using the Newton-Raphson method for the fiber’s linear and angular velocities such that the net hydrodynamic forces and torqu...
متن کاملInfluence of fiber orientation on the inherent acoustic nonlinearity in carbon fiber reinforced composites.
This paper presents the study of non-classical nonlinear response of fiber-reinforced composites. Nonlinear elastic wave methods such as nonlinear resonant ultrasound spectroscopy (NRUS) and nonlinear wave modulation spectroscopy have been used earlier to detect damages in several materials. It was observed that applying these techniques to composites materials becomes difficult due to the sign...
