Single crystals of coordination complexes that show mechanical motion under the influence external stimuli are great interest due to their applications in photoactuators, sensors and probes. The solid-state [2+2] cycloaddition reaction has been one most prominent chemical reactions for photoresponsive materials recent years. However, a relatively limited number compounds have reported, these only shown destructive photosalient effects. Here, we report two photoreactive Zn(II) metal with...
This paper deals with investigations on the active structural–acoustic control of a thin homogeneous isotropic plate using vertically reinforced 1-3 piezoelectric composite (PZC) material. A finite element model is developed for which integrated patch constrained layer damping (ACLD) treatment and coupled an acoustic cavity to describe behavior plate. The constraining ACLD composed PZC Both in-plane out-of-plane actuations by have been utilized deriving model. An experiment also carried out...
Fracture toughness of brittle amorphous polymers (e.g. PMMA) has been reported to decrease with loading rate at low rates and increase abruptly close 5 times its static value very high rates. Dynamic fracture that is much higher than the values attractive technological possibilities. However, reasons for sharp remain unclear. Motivated by these observations, present work focuses on dynamic behavior Polycarbonate (PC), which also an polymer but unlike PMMA, ductile room temperature. The...
The present work deals with the structure of thermo-mechanical stress field near crack-tip in a graded material, where properties vary along crack front an exponential manner. With assumptions steady-state conditions and insulated faces, expansion temperature around is obtained. Results indicate that heat flux radial angular direction has inverse square root singularity crack-tip. gradation does not have any singularity. Navier's equation for system solved using Eigenfunction approach to...
This study explores the formability of laser-welded tailored blanks in context single-point incremental forming (SPIF), a flexible and dieless manufacturing process. Two approaches, variation materials thicknesses, were used to fabricate tailor-welded (TWB) with CRCA DD steel sheets. The quality weld was evaluated by metallographic studies tensile tests. ductility welded joint reduced 81%, hardness increased 133% compared base metal. SPIF employed using hemispherical tool form 'D' shape...
The abdominal aortic aneurysm (AAA) may have a varying degree of calcification where calcium particles are found in different geometrical configurations. impact on the failure aneurysms is not very clear as literature shows contradictory results. This work dedicated to investigating strength an aneurysmatic wall using micromechanical finite element simulations. A Representative Volume Elements (RVE) consisting circular and elliptical generated with volume fractions, which further extruded...
The fracture behavior of notched polycarbonate (PC) is investigated as a function loading rate ranging from quasistatic to dynamic. Complementary numerical simulations are performed using the experimentally obtained load-point displacement input. results indicated that in rage rates considered, initiation toughness PC not sensitive rate. processes near dynamically loaded notch-tip was observed ultra-high speed imaging. In both quasi-static and dynamic loading, defects nucleate ahead notch...
