Numerical analysis of the pullout problem of a fiber embedded in a matrix : comparison with an approximate analytical solution

Esparragoza, Ivan Enrique 20 July 1993 (has links)
The classical problem of pullout of a long elastic rectilinear round bar (fiber) embedded in an elastic half-space (matrix) is considered before and while local debonding occurs. An approximate analytical solution derived from the elasticity theory, the intuitive Saint Venant's principle, the idea of boundary layer in hydrodynamics, and invariant Γ-integrals is presented. The problem is analyzed numerically by means of the finite element method using the ANSYS program. The cases of loading before and after the initiation of the debonding are studied. Both approaches, analytical and numerical, are compared in order to establish the concidence between them. The discrepancy is very small in the global sense though substantial differences appear at particular points.

Methodologies for the optimal design of fibre-reinforced composite structures

Smith, Ryan Elliot January 2003 (has links)
A thesis submitted in compliance with the requirements for the Master's Degree in Technology: Mechanical Engineering, Durban Institution of Technology, 2003. / Composites have become important engineering materials, especially in the fields of automotive, aerospace and marine engineering. This is due to the high specific strength and stiffness properties they offer. At present, fibre-reinforced plastic (FRP) laminates are some of the most common types of composite used. They are produced in various forms with different structural properties. As with all engineering materials, there is the existence of both advantages and disadvantages. One of the main disadvantages is the expense involved in producing both the material and the finished product. The design time is also costly as the material has to be designed concurrently with the structure. / M

Fabrication and mechanical properties of graphite fiber reinforced aluminum alloys

Esashi, Kiyoyuki January 1976 (has links)
A new method to fabricate continuous graphite fiber reinforced aluminum alloy composites has been developed and the tensile properties of the composites have been investigated. Composites with 601, 201 and 7178 alloy matrix containing up to 19 volume per cent of Thornel 50 graphite fiber were studied. These composites showed lower tensile strength values than the expected values from the "rule of mixture". A theoretical model is discussed in order to understand the tensile properties of these composites. In this mechanism, graphite fibers are thought to be broken continuously one after another at maximum loading point of ultimate tensile strength during the tensile test. A further attempt has been made to improve the tensile strength of these composites, based on the above theoretical work. / Applied Science, Faculty of / Materials Engineering, Department of / Graduate
