Thermal Stresses in a Ceramic Composite.

Minimizing Thermal Residual Stresses in Ceramic Matrix Composite by BSG-Starcraft Radius PSO

To achieve an excellent thermal-mechanical performance of CMCs, it is necessary to analyze and design the thickness of the multi-layered interphases for an optimized TRS distribution. An optimization was performed with a new version of the particle swarm optimization, the BSG-Starcraft Radius PSO linked to a finite element software.

Finite-element analysis of thermal expansion and thermal mismatch stresses in a Cu–60vol%ZrW2O8 composite

Thermal mismatch stresses in the ceramic particles of a Cu–ZrW2O8 composite were calculated using a finite-element model, and found to be high enough to trigger a pressure-induced phase transformation, in agreement with previous measurements by X-ray diffraction. The calculated thermal expansion/contraction curves also agree with previous experimental dilatometric results. 2004 Elsevier Ltd. Al...

Transient Thermal Stresses Analysis in a FPGM Cylinder

The present study aims to investigate the analysis of stress, strain, displacement, and electrical potential of a thick hollow cylinder made of FGPM under mechanical and thermal loads. Distribution of mechanical property of material is considered along the shell stick through the power distribution function. Thermal loads have been taken to signify the difference of temperature between outer an...
