ANALYTICAL AND NUMERICAL INVESTIGATION OF ELASTIC STRESSES IN THERMOPLASTIC MATRIX COMPOSITE DISCS UNDER TEMPERATURE EFFECT

Öz

In this study, elastic stress analysis was performed on thermoplastic composite discs. The modulus of elasticity of thermoplastic composite discs is also different from each other. Our goal is to study elastic stretching. The field of application of primitive stresses caused by uneven temperature distribution in engineering is quite large. Under the parabolic temperature distribution of the disks, radial stresses formed on the inner and outer parts of the disks were calculated by assuming that the modulus of elasticity does not change with temperature at temperatures of 30 ° C, 60 ° C, 90 ° C, 120 ° C on the inner and outer surfaces of the disk. During the study, analytical and numerical analysis was performed using a computer program and mathematically modeled ANSYS programs. Both methods give similar results. In other words, the differences dec analytical and numerical results can be ignored. At the end of this study, it was determined that the radial and tangential stress values were higher at high temperatures than at low temperatures. It has been established that tangential stresses are much larger than radial stresses. The purpose of this article is to study the behavior of the thermal load on two different thermoplastic disks.
