Shear effect on dynamic behavior of microcantilever beam with manufacturing process defects

Theoretical prediction of proteins network-induced nonlocal response in molecules-resonator biosensor with hydrogen bonds including van der waals interactions

“…In the other hand, the increase of the average distances ratio (d e /d s ) leads to decrease the shift in frequency over the full range of the relative densityΘand conserve the rotary and shear effects for both EBM and TBM cases. These consequences confirm those indicated in the work published by Bourouina et al [4] for the study of influence of bending stiffness on the dynamics vibration of simply-supported microbeam.…”

“…The remarkable reduction can be explicated as the effect of rotary and shear on the dynamics behavior of the protein-microbeam structure [4,45]. In addition, comparing EBM and TBM, the increase in the substrate length reduces the shift frequency compared with that calculated with small value of the substrate length, for both Hη = 0.1η m and η = 0.5η m examples.…”

“…where I and A in equations denotes respectively, the moment of inertia and the area of cross-section, E and G = E/2(1 + ν) are respectively the Young's modulus and the shear modulus with ν is the Poisson ratio. The parameter k is the shear factor and its value for rectangular microstructures is 5/6 [4,27,29], while (e 0 a) represents the nonlocal parameter that models the influence of small scale on the dynamic of microstructure. The rectangular cross-section of microbeam structure is divided into two laminated layers with a surface nanolayer of thickness t , and another laminated layer with a bulk layer of thickness (2h-2t) as illustrated in figure 1.…”

“…Functional microstructures have become commonplace as physical components in microdevices integrated into Bio-Micro/Electro/Mechanical Systems (Bio-MEMS), featuring reduced volume and low charge for mass sensing of bio-objects [1,2]. These intriguing microcomponents have garnered considerable attention in scientific research and have been integral to multidisciplinary studies, given their advantages of high sensitivity [3,4], enhanced reliability [5], and rapid response [6]. In parallel with the development of functional microstructures, the exploration of physico-chemical behavior has unveiled a realm where practical observations on localized nano-objects, under both natural and artificial conditions [7,8], play a pivotal role.…”

Smart System Modeling and Simulation design of Hemodialysis Machine by SysML with SystemC-AMS

“…These requirements include functional and non-functional requirements, system verification, testing, cost, and schedule. In recent decades, MBSE has been developed to become a powerful tool for the analysis and synthesis of complex systems [8]. the System Modeling Language (SysML) is proposed by the Object Management Group (OMG) [9].…”
