Corrugated beams mechanical behavior modeling by the homogenization method

Modeling Thermo-electro-mechanical Beams in Sugar

INTRODUCTION Qconv SUGAR is a simulation package for 3D MEMS devices that utilizes nodal analysis techniques [1]. It has been shown that nodal analysis is significantly faster than other simulation techniques and can be just as accurate. The latest version of SUGAR (v2.0) includes various models for 2D and 3D beams, electrical beams, and gap closing actuators [2]. In addition, SUGAR is easily e...

mechanical behavior of quasi-sinusoidal corrugated composite sheets

an aircraft wing needs to display different mechanical behavior in different directions. 1- stiffness in the spanwise (transverse to the corrugation) direction which enables the aerodynamic and inertial loads to be carried. 2- compliance in the chordwise (corrugation) direction which would allow shape changes and increases in surface area; whereas a corrugated sheet due to their special geometr...

Shape optimization by the homogenization method

In the context of shape optimization, we seek minimizers of the sum of the elastic compliance and of the weight of a solid structure under specified loading. This problem is known not to be well-posed, and a relaxed formulation is introduced. Its effect is to allow for microperforated composites as admissible designs. In a two-dimensional setting the relaxed formulation was obtained in [6] with...

Atomistic modeling of mechanical behavior

Atomistic modeling plays a critical role in advancing our understanding of microstructure evolution and mechanical properties. We present progresses in the theory and computation of ideal strength, dislocations activation processes and brittle fracture from the atomic perspective, in close connection with experiments and other levels of modeling. New discoveries are often made in the “virtual a...
