Failure under cyclic loading in the presence of manufacturing defects is a substantial risk for additively manufactured (AM) metal components. This study aims to clarify correlation between process-related (internal pores and surface roughness) fatigue performance AM 316 L stainless steel. X-ray computed tomography (XCT) has been employed characterize defects' features their synergistic interaction define effective defect size parameter areaeff, leading identifying potential sites crack...
Elastomeric materials are widely used in different industries due to their excellent capability withstand loading types. There significant challenges the efficient design of elastomeric structures because rate-dependent and highly nonlinear behavior this type material. In study, a damage zone model was employed simulate material evolution polyurethane (PU) elastomers with shore hardness. This consists three sections, hyper viscoelastic constitutive model, initiation, using...
Delamination is the most common failure mode in laminated composites and it leads to loss of structural strength stiffness. In this paper, acoustic emission monitoring was applied on carbon/epoxy when subjected I, II, mixed-mode I II loading conditions. The main objective investigate delamination behavior predict propagation curve different G /G T modal ratio values by emission. First, a combination mechanical data (sentry function) used characterize stage delamination. Next, crack tip...
Additive manufacturing techniques have made it possible to create open-cell porous structures with arbitrary micro-geometrical characteristics. Since a wide range of features is available for making an implant, having comprehensive knowledge the mechanical response cellular very useful. In this study, finite element simulations been carried out investigate effect structure unit cell type (cube, rhombic dodecahedron, Kelvin, Weaire-Phelan, and diamond), cross-section (circular, square,...
In this paper, classical laminate theory is employed to calculate Poisson’s ratios for glass/epoxy, carbon/epoxy, and hybrid composite laminates with various layup configurations. A total number of 67,368,400 different multilayer combinations varying layers, compositions, materials are theoretically analyzed, exhibiting negative ratios. Given the significance showing ratio, auxetic selected from obtained layups, some them further analyzed using experimental finite element methods. The...
Surface effect often plays a significant role in the pull-in performance of nano-electromechanical systems (NEMS) but limited works have been conducted for taking this into account. Herein, influence surface has investigated on instability behavior cantilever nano-actuator presence van der Waals force (vdW). Three different methods, i.e. an analytical modified Adomian decomposition (MAD), Lumped parameter model (LPM) and numerical solution applied to solve governing equation system. The...
