A quarter-circular arc piezoelectric Vibration energy harvester (VEH) based on nonlinear geometry is proposed with both bending moment and torque deformation mode, so it can effectively absorb multidirectional vibration at the same resonance frequency. The theoretical model of VEH established to study frequency output voltage. In order demonstrate multi-directional performance VEH, stress distr...

To enhance the accuracy of mechanical simulation in directional solidification process turbine blades for heavy-duty gas turbines, a new constitutive model that employs machine learning methods was developed. This incorporates incremental and transfer learning, thus improves predictive generalization performance. account anisotropy directionally solidified alloy, deformation direction parameter...

Laser powder bed fusion ( L -PBF) has been the most popular metal additive manufacturing (AM) process thus far. However, residual deformation of builds a significant issue. scanning strategies adopted in laser-assisted fabricating have proved to important influence on stress and deformation. As main contribution this paper, effects different laser are incorporated into modified inherent strain ...

Post processing deformation of additive manufactured components offers many advantages from reduced printing time and material usage to simplified multimaterial fabrication. For thermoplastic components, controlled deformations can be achieved by locally heating to temporarily soften the material. This paper investigates multiple methods of selectively heating and deforming desired locations to...

We show that a dissipative two-dimensional Raman lattice can be engineered in two-component ultracold atomic gas, where the interplay of spin-orbit coupling and lightinduced atom loss gives rise to density flow diagonal underlying square lattice. The is driven by non-Hermitian corner skin effect, under which eigenstates localize toward one system. illustrate topological edge states system only ...

In this study, to explore the microstructure deformation mechanism of marine soft soil under cyclic loading, we analyzed dynamic properties loading via consolidation compression testing. Then, using Image-Pro Plus (IPP) 6.0 image analysis software, and according test results images from a scanning electron microscope (SEM), determined weakening effect soils different confining pressures, stress...

The issue of pressure sensitivity of anisotropic sheet metals is investigated with introducing two new non-AFR criteria which are called here linear and non-Linear pressure sensitive criteria. The yield and plastic potential functions of these criteria are calibrated with directional tensile/compressive yield stresses and directional tensile Lankford coefficients, respectively. To determine unk...
