Viscoplasticity of voided cubic crystals under hydrostatic loading

The total creep of viscoelastic composites under hydrostatic or antiplane loading

The problem of bounding the total creep (or total stress relaxation) of a composite made of two linear viscoelastic materials and subjected to a constant hydrostatic or antiplane loading is considered. It is done by coupling the immediate and the relaxed responses of the composite, which are pure elastic. The coupled bounds provide the possible range of the total deformation at infinite time as...

Nonlinear Finite Element Analysis of Inflatable Prefolded Membrane Structures under Hydrostatic Loading

Quadratic Solitons in Cubic Crystals

Starting from the Maxwell’s equations and without resort to the paraxial approximation, we derive equations describing stationary (1+1)-dimensional beams propagating at an arbitrary direction in an optical crystal with cubic symmetry and purely quadratic (χ) nonlinearity. The equations are derived separately for beams with the TE and TM polarizations. In both cases, they contain χ and cubic (χ)...

Study of flux pinning mechanism under hydrostatic pressure in optimally doped (Ba,K)Fe2As2 single crystals

Strong pinning depends on the pinning force strength and number density of effective defects. Using the hydrostatic pressure method, we demonstrate here that hydrostatic pressure of 1.2 GPa can significantly enhance flux pinning or the critical current density (Jc) of optimally doped Ba0.6K0.4Fe2As2 crystals by a factor of up to 5 in both low and high fields, which is generally rare with other ...

Elasticity and behaviour under magnetic fields of cubic lyomesophases and smectic D liquid crystals

2014 We estimate the shear elastic constant in cubic liquid crystals such as D phases and cubic lyomesophases and find a value, which is about three orders of magnitude less than that of very soft atomic crystals (4He) and three orders of magnitude higher when compared with colloidal crystals. The behaviour under an external magnetic field is discussed and the importance of coupling terms to th...
