In the present study, an elastic-plastic stress analysis is carried out on a composite thermoplastic disc reinforced by steel fibers, curvilinearly. Radial and tangential stresses are obtained under a liner temperature distribution. The magnitude of the tangential stress component for elastic and elastic-plastic cases is higher than that of the radial stress component. The tangential stress component is compressive and tensile on the inner and outer surfaces, respectively and is the highest on the inner surface. The elastic-plastic solution is performed for the plastic region expanded around the inner surface by an analytical formulation and a numerical solution. The solution is also carried out by the finite element method (ANSYS solution). These two solutions give very similar results. The intensities of the residual stress component of the tangential stress and plastic flow are the highest at the inner surface.

Stress analysis of symmetric aluminum composite-laminated beams under a bending moment: Materially nonlinear only Sayman, O; Belevi, M; Altinhan, M (SAGE Publications, 2005-01-01) In this study, an elastic-plastic stress analysis is carried out on symmetric laminated composite beams subjected to a bending moment. The composite beam is to be strain hardening. The Bernoulli and Euler hypotheses are assumed to be valid. The Tsai-Hill theory is used as a yield criterion in the solution. The solution is carried out for (90 degrees/0 degrees)(2), (30 degrees/-30 degrees)(2), (45 degrees/-45 degrees)(2), and (60 degrees/-60 degrees)(2) orientations. The bending moment is to be found the hig...
TENSILE, FLEXURAL AND IMPACT PROPERTIES OF A THERMOPLASTIC MATRIX REINFORCED BY GLASS-FIBER AND GLASS BEAD HYBRIDS Yılmazer, Ülkü (Elsevier BV, 1992-01-01) The tensile and flexural properties, together with the unnotched and notched impact strengths of acrylonitrile butadiene styrene (ABS), glass bead (GB) and glass fiber (GF) ternary composites have been studied. The tensile strengths of the hybrid composites were predicted, from a theory formulated in this study, by using the strengths of the ABS/GB and ABS/GF composites alone. The addition of even a small quantity of glass fiber to ABS or ABS/GB composites changes the mode of deformation from one which sh...
A surface crack in a graded coating subjected to sliding frictional contact Dağ, Serkan; GÜLER, MEHMET ALİ; Gulgec, Mufit (Elsevier BV, 2012-01-01) This article presents an analytical method developed to conduct fracture analysis of functionally graded coatings that are under the effect of contact stresses. The geometric model considered comprises a functionally graded coating, which possesses a surface crack and is perfectly bonded to a homogeneous half-plane. A two-step solution procedure is put forward in which the contact and crack problems are treated separately. First, the graded coating is assumed to be in sliding frictional contact with a rigid...
Effects of processing parameters on mechanical and thermal properties of glass mat reinforced nylon 6 composites Akkaoui, W; Bayram, Göknur (SAGE Publications, 2004-01-01) Nylon 6 (PA6)/Glass Mat (GM) composites and pure PA6 were prepared by compression molding technique and the effects of molding temperature, pressure application time and GM content on the final properties of the materials were investigated. At each temperature and pressure application time, the composite with one layer GM had higher tensile strength, tensile modulus but lower % elongation at break than neat PA6. Processing parameters did not significantly influence the tensile behavior of the pure PA6 and P...
Inter-granular cracking through strain gradient crystal plasticity and cohesive zone modeling approaches Yalçınkaya, Tuncay; Fırat, Arzu (Elsevier BV, 2019-10-01) Even though intergranular fracture is generally regarded as a macroscopically brittle mechanism, there are various cases where the fracture occurs at the grain boundaries with considerable plastic deformation at the macroscopic scale. There exists several microstructural reasons for grain boundaries to host crack initiation. They can interact with impurities and defects, can provide preferential location for precipitation, can behave as a source of dislocations and can impede the movement of dislocations as...
