We consider the von Kármán nonlinearity and the Casimir force to develop reduced-order models for prestressed clamped rectangular and circular electrostatically actuated microplates. Reduced-order models are derived by taking flexural vibration mode shapes as basis functions for the transverse displacement. The in-plane displacement vector is decomposed as the sum of displacements for irrotatio...

Abstract This work addresses the design of miniature compliant displacement amplifiers. The optimum mechanism is generated through topology optimization two-node frame elements with linearly varying cross sections using Ant Colony Optimization technique. First, stiffness matrices that account for change in cross-section dimensions are formulated. Then, each element assigned 5 independent ants r...

In recent years, computer vision-based structural displacement acquisition technique has received wide attention and research due to the advantages of easy deployment, low-cost, non-contact. However, field large-scale structures is a challenging topic as result contradiction camera field-of-view resolution. This paper presents calculation framework with integrated vision physical constraints us...

In this paper, the closed form analytical expressions for the displacement field due to a cylindrical inclusion in a thermoelastic half-space are obtained. These expressions are derived in the context of steady-state uncoupled thermoelasticity using thermoelastic displacement potential functions. The thermal displacement field is generated due to differences in the coefficients of linear therma...

in the present research, the effects of delamination size and location on vibration characteristics of laminated composite beams are investigated both analytically and numerically. in the analytical method, the delaminated beam is modeled as four interconnected euler–bernoulli beams and the constrained and free mode models are both simulated. the differential stretching and the bending-extensio...

This study describes a wireless laser displacement sensor node that measures displacement as a representative damage index for structural health monitoring (SHM). The proposed measurement system consists of a laser displacement sensor (LDS) and a customized wireless sensor node. Wireless communication is enabled by a sensor node that consists of a sensor module, a code division multiple access ...

cardiac conduction system enables the heart to pulsate continuously by producing electric impulse and conducting it. as the anatomical information about cardiac conduction system in human being and other mammals needed in various fields of sciences, such as anatomy, histology, physiology, pathology and cardiology, the present review article intends to provide this basic information about an imp...

Error estimation and adaptive applications help to control the discretization errors in finite element analysis. The study implements radial point interpolation (RPI)-based error-recovery approaches displacement/pressure-based mixed approach is used formulation. RPI considers basis functions (RBF) polynomials together interpolate solutions, i.e., displacement over influence zones recover soluti...
