Among the strategies for achieving ceramics with improved mechanical properties, especially toughness, some involve the engineering of microstructures that either resist the propagation of cracks or absorb energy during the crack propagation process.
It was shown in the 1970s that zirconia exhibits a transformation toughening mechanism acting to resist crack propagation.
The elastic-modulus-graded environmental barrier coatings (EMG-EBCs) were designed and fabricated to resist crack propagation in this study.
Interfaces such as grain, sub-grain and interphase boundaries are microstructural features that can resist crack propagation.
The car which is actually involved in accident is equipped with tamper-proof component to resist against propagation of fake identities.
The tougher α + β mixture can help resist the propagation of fatigue cracks by crack blunting and thus improve the fatigue properties.
In this work, electrospun gelatin nanofibres, mimicking the collagen network in native tissues, are used to strengthen and resist crack propagation in brittle alginate hydrogels.
GNS pull-out, grain bridging by GNS, crack bridging and crack deflection are the major toughening mechanisms that resist crack propagation.
The target experiment model is designed as a three-compartment box, an air, a fluid and another air compartment, which is made of four plates with thickness 4 mm that resist the propagation of damage.
Furthermore, the capability of polypropylene fiber to resist crack propagation of CTCR appears to be becoming stronger and stronger with the increase of fiber volume fraction with the fiber volume fraction not beyond 0.1%.
