Previous inversions for slip rate along the San Andreas Fault System (SAFS), based on elastic half-space models, show a discrepancy between the geologic and geodetic slip rates along a few major fault segments. In this study, we use an earthquake cycle model representing an elastic plate over a viscoelastic half-space to demonstrate that there is no significant discrepancy between long-term geo...

A method is proposed to identify the mechanical properties of the skin and core materials of sandwich structures having heterogeneous cores. All the elastic coefficients and loss-factors that matter in the dynamics of such a panel in the thick-plate approximation are identified. To this end, experimental natural modes (i.e. eigenmodes of the damped system) are compared to the numerical modes of...

The method for calculating the deflection of a web-core sandwich panel in its weak direction is based on complex shell and plate theory. A simple method was presented by assuming inflection points are located at the mid-span of the facing plate segment between two adjacent web cores. It also assumes that an inflection point also exists at the midheight of the web core. Based on these assumption...

The paper deals with the computation of residual and transient stresses in a tempered glass plate. The modelling takes into account the viscoelastic behavior and the structural relaxation of glass. The evolution of stresses with time during the rapid cooling is computed. Simulation results are compared with experimental ones from the literature available. Levels of transient tensile stress in t...

A 96-well plate sandwich assay based on Invader capture/signalling probes is used to recognize 28-mer mixed-sequence dsDNA targets specific to Salmonella enterica, Campylobacter jejuni, Escherichia coli. Targets are detected down to 20-55 pM concentration with excellent binding specificity.

Based on the third-order shear deformation theory (TSDT), this paper numerically investigates the natural frequencies and time response of three-layered annular plate with functionally graded materials (FGMs) sheet core and piezoelectric face sheets, under initial external electric voltage. The impressive material specifications of FGM core are assumed to vary continuously across the plate thic...

The present study investigates the buckling of a thick sandwich plate under the biaxial non-uniform compression using the modified couple stress theory with various boundary conditions. For this purpose, the top and bottom faces are orthotropic graphene sheets and for the central core the isotropic soft materials are investigated. The simplified first order shear deformation theory (S-FSDT) is ...

The seismic performance of reinforced concrete (RC) columns retrofitted using the steel plate sandwich method bonded with prestressed PC bars was compared in both in-plane and out-of-plane directions. Therefore, bending strength, initial horizontal rigidity, cumulative energy absorption improved.

In this article a new structure of PEM fuel cell end plate is presented. The new structure is known as a honeycomb sandwich panel. Several properties of the presented structure, such as mechanical and thermal behavior, as well as its advantages and disadvantages are introduced. The aim of this paper is to reduce the weight of the while maintaining a better compression force on the PEM fuel cell...
