Propagation phenomena in a visco-thermo-micropolar elastic medium under the effect of micro-temperature

open access: yesResults in Physics, 2018
The analysis is made on reflection of waves in thermoelastic micropolar medium. The medium is having an additional property of viscosity, while studying waves the effect of micro-temperature is also been considered.

Four simplified gradient elasticity models for the simulation of dispersive wave propagation [PDF]

open access: yes, 2008
Gradient elasticity theories can be used to simulate dispersive wave propagation as it occurs in heterogeneous materials. Compared to the second-order partial differential equations of classical elasticity, in its most general format gradient elasticity ...

Second-Order Strains of Lignostone Under Creep and Constitutive Equations

open access: yesEngineering Transactions, 1993
Specimens of the beech wood lignostone are tested for creep under simple tension along the grain and torsion, respectively. The second-order strains (interrelated strains) 2l12 and l11 generated in result of pure tension and torsion are found to be ...

Constitutive models of pavement asphaltic layers based on mixture compositions

open access: yesJournal of Civil Engineering and Management, 2017
The design of flexible and semi-rigid pavements by applying mechanistic-empirical methods involves the determination of the stress and strain states in accordance with the assumptions of continuum mechanics. Advanced computational models should take into
