Deflection analysis of a simply supported microbeam subjected to a concentrated load at the middle is investigated on the basis of a shear deformable beam theory and non-classical theory. Effects of shear deformation and small size are taken into consideration by hyperbolic shear deformable beam theory and modified strain gradient theory, respectively. The governing differential equations and c...

The accuracy of the Theory Critical Distances, Gradient Elasticity and Averaged Strain Energy Density criterion in estimating fatigue lifetime notched additively manufactured Ti6Al4V is assessed against numerous experimental results generated under load ratios equal to ?1 0.1. 3D-printed Ti-alloy investigation was tested by keeping notches as-manufactured condition. common feature considered de...

Based on a hydrogenic state and strain changes upon defect charging, we propose a simple, parameter-free model that agrees well with the observed group III and V monovalent-impurity ionization energies in Si, revealing the importance of such strain effects. Changes in lattice strain upon defect charging are obtained via superposition and elasticity theory using atomic relaxations from density f...

We propose a family of mixed finite elements that are robust for the nearly incompressible strain gradient model, which is fourth-order singular perturbed elliptic system. The element similar to [C. Taylor and P. Hood, Comput. & Fluids, 1(1973), 73–100] in Stokes flow. Using uniform discrete B-B inequality pairs, we show optimal rate convergence limit. By new regularity result both materials pa...

Young's modulus determines the mechanical loads required to elastically stretch a material, and also, bend it, given that bending stretches one surface while compressing opposite one. Flexoelectric materials have additional property of becoming electrically polarized when bent. While numerous studies characterized this flexoelectric coupling, its impact on response, due energy cost polarization...
