WebbThe classical linear elasticity provides a description of material behaviour, which is sufficiently accurate for many practical applications. Nonetheless, while modelling such materials, as for example cellular material, fibers and human bones, a more accurate material model describing not only displacement, as in the case of classical elasticity, … WebbTheories of Failure Strength of a material or failure of the material is deduced generally from uni-axial tests from which stress strain characteristics of the material are obtained. The typical stress-strain …
WebbThe dissolution of minute concentration of polymers in wall-bounded flows is well-known for its unparalleled ability to reduce turbulent friction drag. Another phenomenon, elasto-inertial turbulence (EIT), has been far less studied even though elastic instabilities have already been observed in dilute polymer solutions before the discovery of polymer drag …
