A two-dimensional molecular model is presented for the elastic non-linear modelling and design of meta-materials. The fundamental unit-cell, based on a heuristic molecule (HM) approach, composed atoms that interact through centred non-centred spring-based bonds. kinematics formulation allows to consider large displacements finite strains while specific topology HM can be parametrized modify sha...

We study a free transmission problem in which solution minimizes functional with different definitions positive and negative phases. prove some asymptotic regularity results when the jumps of diffusion coefficients get smaller along boundary. At last, we measure-theoretic result related to

Discussion
 With the incorporation of International Journal Small Craft Technology into IJME, it is always good to see papers direct concern small craft design community. The process on-going validation scantling rule formulae also be welcomed. authors are commended on both counts. Word count restricts comments/questions ultimate flexural strength hand-laminated panels (Table 5).

The titled problem of coupled thermoelasticity for porous structure has been solved with an instantaneous heat source acting on a plane area in an unbounded medium. The basic equations of thermoelasticity, after being converted into a one-dimensional form, have been written in the form of a vector-matrix differential equation and solved by the eigenvalue approach for the field variables in the ...

In this paper the propagation of harmonic plane waves in a homogeneous anisotropic magneto-piezothermoelastic diffusive body with fractional order derivative is studied. The governing equations for a homogeneous transversely isotropic body in the context of the theory of thermoelasticity with diffusion given by Sherief et al. [1] are considered as a special case. It is found that three types of...

We measure polarization-resolved instantaneous patterns in a large-aspect ratio quasi-isotropic Nd:YAG laser. High correlation between the instantaneous orthogonal polarization patterns recorded at the earlier stages of the laser pulse has been found due to the strong cross saturation between both polarization modes.

The incoherent quasi elastic cold neutron scattering data of the side chain dynamics of the backbone deuterated linear polymer polyacrylate of Benguigui et al. (J. Phys. II France 1 (1991) 451), have been successfully interpreted in the isotropic, smectic A and re-entrant nernatic
