The shear, or strain, rate is often calculated based on the square root of the second invariant of rate-of-strain tensor. The tensor itself is made up of all the possible deformation of a fluid element, which includes volumetric and shear deformation. I would like to invite comments from ...

11, layered metal chalcogenides12,13,14,15,16and artificial photonic structures17,18. However, these materials in general exhibit weak effective[Math Processing Error]χ(2)susceptibilities (which is the product of the[Math Processing Error]χ(3)susceptibility and electric field) and low modulation...
The outcome of the first Challenge motivated this second Challenge, which explores several new facets: (1) in addition to quasi-static loading, the scenario also involves modest dynamic loading spanning three orders of magnitude in strain-rate, (2) the sharp-crack fracture toughness data is repla...
A relationship between noncoaxial tensors of stress and creep strain rate is established for the case of plane strain or a plane stress state. The basis is the experimentally substantiated hypothesis on the existence of a creep surface, which is a set of loading paths in the stress space ...
In view of this, the proposed model is simple and somewhat more realistic, in the sense that contact torques do not exist in nonpolar EAPs. Keywords: fibre-reinforced electroactive polymers; bending stiffness; spectral invariant; nonpolar; hyperelasticity...
It is obvious that especially for linear time-invariant (LTI) systems that are composed of structures described by material models considering higher gradients of the kinematical variables, the question of system identification needs further discussion. Contributing to this discussion is the motivation for...
