A stress-based finite element approach to the Reissner-Mindlin plate bending problem is proposed. The rectangular Bogner-Fox-Schmit and triangular Hsieh-Clough-Tocher elements are applied to approximate the Southwell stress function describing the statically admissible stress field in a plate. To have some reference…

This article aims to improve the real-time monitoring accuracy of the loss rate for grain combine harvesters by optimizing the sensor-sensitive plate structure, thereby addressing the problem of low detection efficiency in existing equipment. Based on Kirchhoff’s thin plate theory, COMSOL 6.0 software was utilized to…

Piezoelectric plates, which become electrically polarised in response to bending, have recently been proposed for water wave energy conversion. However, piezoelectric materials (e.g. Polyvinylidene Fluoride) can be anisotropic, which makes them challenging to model in three dimensions. This paper considers the simpler…

We study the interaction between gravitational waves and elastic bodies within the framework of relativistic elasticity. Starting from the Lagrangian formulation of relativistic elasticity, we derive the linearized equations governing the response of a homogeneous and isotropic solid to a weak gravitational wave by…

This work presents a modal formulation for flexible rectangular plates, accounting for nonlinear geometric effects arising from in-plane foreshortening and centrifugal stiffening. The model is linearized with respect to elastic deformations while retaining the full dependence on spacecraft angular velocities and…

Highlights 1. The coupling B-submatrix has an effect on the buckling behaviour of thin-walled laminated plates. 2. The inclusion of the coupling B-submatrix leads to decreased bifurcation loads. 3. Coupling effects represented by the B-submatrix result in stiffness reduction coefficients within the beam model. Abstract…

This manuscript introduces a novel induction heating platform designed to enable multiplexed temperature screen for microscale high-throughput reactions through remote, wireless heating in multi-well plates. This approach employs metal balls within the wells to efficiently convert surrounding electromagnetic energy…

Turbulent boundary layers characterised by friction Reynolds numbers in the range $Re_τ = 880 - 1460$ and flowing over flush-mounted passively rotating discs are investigated in a wind tunnel with the purpose of reducing the skin-friction drag. The test surface is composed of thirty-two rotating discs arranged in a…

This study considers the dynamic stability of a three-layered annular plate, whose facings are made of functionally graded material in the radial direction. The plate is subjected to linearly increasing in-plane forces applied at either the inner or outer edge. The effect of the heterogeneity of the plate-facing…

Generating novel, drug-like molecules with realistic synthetic pathways is an essential goal in computer-aided drug discovery, yet generative models often lack synthesis awareness, resulting in compounds that are difficult or impossible to produce. To overcome this limitation, models must optimize not only molecular…

In vitro experimental radiobiology is a fundamental tool for understanding the cellular and molecular mechanisms involved in the response to ionizing radiation. Conventional experimental designs require separate irradiations to achieve different absorbed doses, thereby introducing experimental variability between…
