Velocity Jump of Crack Propagation in Viscoelastic Solids
نویسندگان
چکیده
A crack in a viscoelastic solid exhibits velocity jump, i.e., the propagation changes abruptly narrow range of applied load. However, mechanism had been unsolved until recently. This review introduces past findings on jumps solids, focusing our studies. We have developed an exactly solvable model that jump. From mathematical solution, we elucidated jump is caused by dynamic glass transition vicinity tip. Also, provided guiding principle for toughening solids. Recently, predictions confirmed experiments and numerical simulations.

Crack propagation in viscoelastic solids.
We study crack propagation in a viscoelastic solid. Using simple arguments, we derive equations for the velocity dependence of the crack-tip radius, a (v) , and for the energy per unit area to propagate the crack, G (v) . For a viscoelastic modulus E (omega) which increases as omega(1-s) (0< s< 1) in the transition region between the rubbery region and the glassy region, we find that a (v) appr...
متن کاملMechanisms of fatigue-crack propagation in ductile and brittle solids
The mechanisms of fatigue-crack propagation are examined with particular emphasis on the similarities and differences between cyclic crack growth in ductile materials, such as metals, and corresponding behavior in brittle materials, such as intermetallics and ceramics. This is achieved by considering the process of fatiguecrack growth as a mutual competition between intrinsic mechanisms of crac...
متن کاملWave Propagation in Mixture of Generalized Thermoelastic Solids Half-Space
This paper concentrates on the reflection of plane waves in the mixture of generalized thermo elastic solid half-space. There exists quasi dilatational waves i.e. qP1, qP2, qT and two rotational waves S1, S2 in a two dimensional model of the solid. The boundary conditions are solved to obtain a system of five non-homogeneous equations for amplitude ratios. These amplitude ratios are found to de...
متن کاملA Model for Predicting the Multiscale Crack Growth Due to an Impact in Heterogeneous Viscoelastic Solids
A two-scale model for predicting the multiple crack growth in viscoelastic solids due to an impact is presented. The cracks are considered only at the local scale through the use of a micromechanical viscoelastic cohesive zone model. The multiscale model has been implemented in a finite-element code. In order to minimize the computation time, the local finite-element meshes are solved in parall...
متن کاملLubrication of soft viscoelastic solids
Lubrication flows appear in many applications in engineering, biophysics, and in nature. Separation of surfaces and minimisation of friction and wear is achieved when the lubrication fluid builds up a lift force. In this paper we analyse soft lubricated contacts by treating the solid walls as viscoelastic: soft materials are typically not purely elastic, but dissipate energy under dynamical loa...
