Abstract:
To study the impact response characteristics of multilayer structure, cantilever-type electrothermal actuators based on MEMS, a composite cantilever-beam model consisting of two layers of materials, SiO2 and Al, is built. By using the engineer mechanics theory, the von mise stress under the impacts in the fuze system can be obtained. Meanwhile, the Finite Element Method (FEM) simulation is made to get the deformation displacement of the fixed end and the von mises stress distribution of the model. Besides, the natural frequency response is studied. The results present the actuators response ch

Abstract:
This paper addresses an important issue of the individual layer thickness influence in a multilayer piezo composite on electro-mechanical energy conversion. The use of energy harvesting systems seems to be very promising for applications such as ultra-low power electronics, sensors and wireless communication. The energy converters are often disabled due to a failure of the piezo layer caused by an excessive deformation/stresses occurring upon the operation. It is thus desirable to increase both reliability and efficiency of the electromechanical conversion as compared to standard concepts. The

This paper focuses on the latest development of a solid hexahedron element for composite delamination analysis. The 8-node solid is derived from a 20-node hexahedron. It is transformed into two physical independent 4-node shell elements according to the propagation of delamination process within the element. This transformation is driven by a transfer and damage laws that are defined by calibrating the element with a FE modeling for a double cantilever beam (DCB) test. According to the position of the crack in the element, one parameter defines the degradation of the transverse properties at t

This study addresses the analytical treatment of a closed-form buckling equation for lateral-torsional stability of thin web composite cantilever beams under mid-height tip force. The beam is composed of random ply fiber orientations. Classical lamination theory is embedded into the Vlasov plate formulation to make up the framework of the analytical treatment. A closed-form solution is realized when an innovative dimensional reduction is extended to the 3D constitutive stiffness matrix. This was made possible through a two-step process in which the shear strain, lateral curvature, and twisting

The composite T-girders include concrete flange plates and steel beams, which are connected by shear connectors. The longitudinal stress about concrete plate is due to non-uniform distribution on cross section because of the shear lag effect. A differential equation of longitudinal forces at transverse section flange and cantilever flange is separately established according to the strain compatibility and the force equilibrium conditions about a composite T-girder. The method of separation of variables is used to solve the differential equation about the simply supported composite T-girder. Th

The paper presents an effective method for achieving the optimum design of composite structures subjected to multiple displacement constraints. Based on the optimality criterion method and some approximate engineering assumptions, this paper introduces a simplified expression relating the design variables to Lagrange multipliers, which correspond to displacement constraints. Therefore, the optimal design variables are derived from a smaller number of unknown coefficients. Thus the computational efficiency is greatly enhanced. Furthermore, the multilevel optimization technique is adopted. The o

Water jet piercing of composite laminates finds a wide application in varying fields of manufacturing, but has an inherent problem of delamination which restricts its usage. This paper makes an attempt to successfully make smaller diameter holes using impulse water jet. Both experimental and theoretical results confirmed that while piercing of composite laminates using water jet the defects appear in between the layers of laminates which may be due to bending moment of the bottom plies, which is because of the high pressure jet involved in piercing process.

Bending properties and interlaminar properties of TFS beams with various foam densities were investigated by flexural tests and DCB (double cantilever beam) tests. The test results showed that by increasing the foam core density from 35 kg/m3 to 150 kg/m3, the peak strength of TFS beams significantly increased by 168% to 258% compared with similar sandwich be

A directionally attached piezoelectric (DAP) actuator is one method to control the twisting vibration of a plate with high authority. Although insuring proper performance for DAP actuators has been discussed in terms of the control law used, the optimization of the mechanical details of the actuator itself has received little attention. There is an interaction between the actuator and the controlled structure because more actuator material on the structure adds actuation power but also stiffens the structure.

The flexoelectric coefficient of the bilayer BST film multilayer structure is 1.66 μC/m, which doubles the effective flexoelectric coefficient comparing to the single layer BST. In addition, we discussed the effective piezoelectric coefficient of the BST film multilayer structure, which can reach as much as 2.
