Fracture Problems in Composite Materials
In this paper a series of fracture problems in composite materials are identified, their methods of solution are briefly discussed, and some sample results are presented. The main problem of interest is the determination of the stress state in the neighborhood of localized imperfections such as cracks and inclusions which may exist in the composite. Particular emphasis is placed on the evaluati...
متن کاملPhase Field Modeling of Fracture and Composite Materials
The phase field method is a very powerful numerical method to solve moving boundary problems. Here we demonstrate how it can be applied to various processes involving sound propagation and fracture. This approach is related to a new theory of fracture which describes in particular the fast growth of cracks. We study the propagation of elastic waves, the determination of stress intensity factors...
متن کاملThe 19 International Conference on Composite Materials Biomechanical Properties of Resorbable Composite Bone Fracture Repair Plates
Current bone repair implants for use within the body are made from metals [1, 2], which have disadvantages such as stress shielding and can remain in the body permanently. In addition, a fractured bone fixated with a metal plate may re-fracture upon removal of the implant [3].This is due to the fact that bone does not carry sufficient load during the healing process. Recently, a move towards de...
متن کاملModeling of Hygrothermal Damage of Composite Materials
Composite materials have been used extensively in various applications, such as mechanical engineering, aerospace engineering, and aviation thanks to their interesting mechanical properties. However, a substantial drawback in the use of such composite materials is that they absorb a significant amount of moisture when exposed to severe hygrothermal conditions. This factor dramatically affects t...
متن کاملFailure Criteria Analysis of Laminate Composite Materials
This paper deals with the development of a numerical simulation methodology for estimating damages in laminate composite materials caused by a low-speed impact. Experimental tests were performed on laminate plates reinforced with woven carbon fibers and epoxy resin. Three thickness plates were evaluated. The impact loads were transversal and punctual. Two lamina failure criteria were evaluated....
