A new interface fracture test was developed for ceramic environmental barrier coatings (EBCs) on matrix composites (CMCs). The proposed modifies an existing in order to simplify specimen preparation. An asymmetric double cantilever beam (ADCB) with a stiffener adhering the coating used, and wedge inserted into notch open it. formula calculate toughness using opening load displacement derived; i...

The structure optimization design under thermo-mechanical coupling is a difficult problem in the topology field. An adaptive growth algorithm has become more effective approach for structural optimization. This paper proposed method by an stiffener layout of box type load-bearing components coupling. Based on stiffness diffusion theory, both load matrix and heat conduction are spread at same ti...
