Abstract The properties of materials and structures typically remain fixed after being designed manufactured. There is a growing interest in systems with the capability altering their behaviors without changing geometries or material constitutions, because such reprogrammable could unlock multiple functionalities within single design. We introduce an optimization-driven approach, based on multi...

Tailored materials are of particular interest in modern engineering applications due to their potentially high strength and residual ductility. During hot forming processes, such as press hardening, microstructure transformations low carbon steels considered achieve the production tailored components. The relevant mechanisms during thermo-mechanical processing visco-plastic deformation phase tr...

In this study, using the non-local elasticity theory, the buckling and vibration analysis of triple- walled ZnO piezoelectric Timoshenko beam on elastic Pasternak foundation is analytically investigated under magneto-electro-thermo-mechanical loadings. Using the Timoshenko beam free body diagram, the equilibrium equation of Timoshenko nano-beam model is obtained and solved by Navier’s method fo...

Poly(lactic acid) (PLA) is a green alternative to petrochemical commodity plastics, used in packaging, agricultural products, disposable materials, textiles, and automotive composites. It is also approved by regulatory authorities for several biomedical applications. However, for some uses it is required that some of its properties be improved, namely in terms of thermo-mechanical and electrica...

We report on the formation of a stable Body-Centered Heptahedral (BCH) crystalline nanobridge structure of diameter ~ 1nm under high strain rate tensile loading to a <100> Cu nanowire. Extensive Molecular Dynamics (MD) simulations are performed. Six different cross-sectional dimensions of Cu nanowires are analyzed, i.e. 0.3615 x 0.3615 nm, 0.723 x 0.723 nm, 1.0845 x 1.0845 nm, 1.446 x 1.446 nm,...

The purpose of this work is to use 3D finite element analyses to compute bending of a hard disk suspension using a laser. The pitch and roll of the suspension can be precisely adjusted by producing a controlled amount of residual strain using the laser as a heat source. In the computational model, an uncoupled thermo-mechanical analysis is applied to calculate the laser induced thermal loading ...

Turbine blades are working under complex thermal gradient mechanical loading conditions. In the present study, a nickel-based single-crystal superalloy CMSX-4 is experimentally and computationally investigated thermo-mechanical fatigue (TMF) (TGMF) conditions of in-phase out-of-phase thermal-mechanical angel. The life TGMF with without barrier coating was studied. It confirmed that lifetime aff...

A comprehensive computational framework based on the finite element method for the simulation of coupled hygro-thermo-mechanical problems in photovoltaic laminates is herein proposed. While the thermo-mechanical problem takes place in the three-dimensional space of the laminate, moisture diffusion occurs in a two-dimensional domain represented by the polymeric layers and by the vertical channel...

A facile method termed magneto-mechanical drawing is used to produce polymer composite microfibers. Compared with electrospinning and other fiber spinning methods, magneto-mechanical drawing uses magnetic force generated by a permanent magnet to draw droplets of polymer/magnetic nanoparticle suspensions, leading to fabrication of composite microfibers. In addition, because of the rotating colle...
