where KIc is the Mode I fracture toughness (critical KI value), κ=3-4ν for plane strain and κ=(3-4ν)/(1+ν) for plane stress. Equation (16) represents the maximum energy release rate, which can be used for the prediction of the direction of crack propagation. Equation (17) pro...
With the miniaturization of feature size, size effect is the main problem in micro forming process and material behavior. In the paper, the size effect of foil thickness on deformation behavior and fracture was investigated by using uniaxial tensile test of 316L stainless steel sheet. The tensile...
29. For example, Wooseong et al.24prepared a ultrathin and porous poly(vinyl alcohol) nanofibers (PVA NFs) substrate using electrospinning process to create a PVA NFs/Au-based humidity sensor. The volume of PVA NFs expands/shrinks when absorbing/desorbing water, causing the fracture and recov...
In order to increase the laser damage threshold, an additional protective layer of silicon oxide was deposited on the Mo2C. The FM is a single-layer structure of 20 μm, and its high elasticity makes it not easy to fracture. The transmission rate of FM is as high as 90% at near ...
When the deformation exceeds the fracture strain, the damage mode of the wall plates changes from mode I to mode II. Subjected to the same internal blast load, wall plates with a smaller area are more likely to obtain the critical velocity and are more easily converted from damage mode III...
[6] observed strong correlation between the tensile and bend fracture limits of extruded AZ80 sheet, Desinghege et al. [8] showed for AZ31 that there is a clear difference between the yield strength in bending and tension and related this to the tension/compression yield mismatch. One of ...
It was a hard hit, and I think most of my damage (compression fracture to vertebrae T-11 and broken rib at T-12) happened where the pictures show me coming OUT of the gravel trap. There was about an 18" high ridge of dirt they cut into the ground for the hole for the gravel...
Test results proved that dissimilar metals namely Ti and Al alloys are amenable for welding using laser beam by selecting appropriate process parameters.KEYWORDS: Ti/Al; Welding; Tensile strength; Fracture mode.K. KalaiselvanA.ElangoNM.Nagarajan...
It is shown that the fracture of recycled thin sheet metals is tough due to the large plastic deformation, and mixed-mode crack is easier to extend than mode I crack. The critical CTOA at stable crack tearing is constant and can be used as a fracture criterion for the thin sheet metals....
