Fracture and toughening of soft elastic composite
Characterized by their low modulus and high stretchability, soft composites have recently attracted great interest from researchers in related areas. The main objective of the present study is on the fracture property and toughening mechanism of soft composites. Two types of soft composites will be studied: soft elastic foam and the double-network (DN) composite. A theoretical/numerical study i...
متن کاملToughening by Crack Deflection in the Homogenization of Brittle Composites with Soft Inclusions
We present a simple example of toughening mechanism in the homogenization of composites with soft inclusions, produced by crack deflection at microscopic level. We show that the mechanism is connected to the irreversibility of the crack process. Because of that it cannot be detected through the standard homogenization tool of the Γ-convergence.
متن کاملTransformation Plasticity and Toughening
Analysis of the dynamic evolution of multilevel structure during martensitic transformations provides kinetics-based constitutive relations for transformation plasticity. Application in numerical modeling of ductile fracture by microvoid-softening-induced shear localization, in conjunction with metallographic study of crack-tip processes, identifies transformation toughening mechanisms operatin...
متن کاملAmorphous intergranular films as toughening structural features
The ability of amorphous intergranular films to mitigate damage formation at grain boundaries is studied with molecular dynamics simulations. We find that such films can alter both crack nucleation and crack growth rates by efficiently absorbing dislocations, with thicker films being more effective sinks. Local plastic strain brought by incoming dislocations is diffused into a triangular region...
متن کاملFollow-up in soft tissue sarcomas
The strategy for the follow-up of soft tissue sarcomas (STS) after therapy is tailored to the individual risk of recurrence and based on efficient rather than sophisticated methods of observation. Along with advances in the treatment of sarcomas, earlier detection of a less advanced and resectable recurrent disease (local or metastasis-especially to the lungs) can prolong patient survival. Sinc...
