... process. In LWJ machining, a 200 W power laser was used for local heating followed by waterjet quenching of the sample surface leading to thermal shock fracture in the heated zone. Experimental results indicate three characteristic fracture responses: scribing, controlled separation, and uncontrolled...

... and crack size. Crack propagation behavior is discussed. The parameters that control the transient thermal stress and electric fields are also identified. The maximum thermal shock strength that the material can sustain without catastrophic failure is established according to two distinct criteria: (i...

...). Crack growth under a single heating-cooling cycle simulating a laser thermal shock experiment is considered. The traction-separation relations for YSZ and BC alloy are coupled to yield a traction-separation relation for the individual layers of the graded TBC. Results from laser thermal shock...

...Y. C. Zhou; S. G. Long; Z. P. Duan; T. Hashida Thermal damage of SiC particulate-reinforced aluminum composites (MMCs) caused by laser thermal shock was investigated. The damage was induced by a combination of laser beam thermal shock and mechanical loads. The MMCs have two kinds of particle...
