Electro-thermo-elastic formulation for the analysis of smart structures
TL;DR: In this article, coupled electro-thermo-elastic equations applicable for the analysis of smart structures with piezoelectric patches/layers have been derived from the fundamental principles of mass, linear momentum, angular momentum, energy and charge conservation.
Journal ArticleDOI
Linear and Nonlinear Analysis of a Smart Beam Using General Electrothermoelastic Formulation
TL;DR: In this article, coupled electrothermoelastic equations applicable to the analysis of smart structures have been derived from first principles, and applying a layer-by-layer finite element model, the induced potential and mechanical deformations in the piezo and non-piezo core material have been obtained for various cases of actuation and sensing of a smart beam under external mechanical load and actuation potential.
Journal ArticleDOI
Electroelastic analysis and layer-by-layer modeling of a smart beam
TL;DR: Using laws of conservation, a general electrothermoelastic formulation has been developed for the analysis of smart structures based on this formulation a layer-by-layer finite element model was developed using variational principle as mentioned in this paper, which effectively captured the continuity of shear stress across the interface between piezolayers and the metallic host material.
Journal ArticleDOI
Mechanical and tribological behavior of TiB2/ Al2O3 coating on high-speed steel using electron beam deposition
Ajaz S Ali,Sheikh N. Ahmad +1 more
TL;DR: In this paper , the effect of load on Young's modulus and hardness was studied using mechanical experiments on TiB2-Al2O3-Ti(20 %) coatings at modest loads ranging from 2000 to 10000 µN.
Journal ArticleDOI
Corrosion behaviour OF HVOF deposited Zn–Ni–Cu and Zn–Ni–Cu–TiB2 coatings on mild steel
TL;DR: In this article , the authors used high-velocity oxy-fuel (HVOF) thermal spray technique on a mild steel substrate and found that Zn-Ni-Cu and Zn−Ni−Cu−TiB2 coatings performed significantly better compared to uncoated mild steel in corrosive environments.
