the constituents in a composite material may result in residual stress which is called "thermal mismatch" stress upon cooling or heating again in service[1-3]. This thermal mismatch stress is usually several times bigger than that of the thermal gradient stress, sometimes even one or two order of magnitude. Such stress often results in micro-crack, which always decreases mechanical strength. Recently......
