This suggests that, for an sp.info 1Effect of a stringer on the stress concentration due to a 4 NACAZ!l!l4207 * the end of the idealizedcrack is a measure of the stress concentration due to a thin crackwith a small, but nonzero, radius of curvature at its v end. The effect of the stringer on the [email protected] of the stress singularity is found by solving the two similarproble~ of the cracked sheetwith and without the stringer. The desired correctionfactor previously defined is sp.info Effects of mean stress and stress concentration on fatigue Jul 27, 2015 · Effect of stress concentration was found to be considerable, with or without mean stress and in both the longitudinal and transverse directions. The commonly used Neuber's rule for metallic materials, nonlinear finite element analysis, as well as critical distance approaches were utilized for notch deformation and fatigue life analyses.

Oct 06, 2016 · An example is a the stress concentration at a hole. Sudden changes increase the value of stress concentration. This must be taken into account when designing structures – even if the whole part has been designed with a high safety factor, there could still be areas where local stress values are higher than the ultimate tensile strength of the sp.info THE EFFECTS OF MEAN STRESS AND STRESS It has been shown that the allowable amplitude of shear stress on this plane can be predicted from an equation of the form τ a = [t ‐ c 1 (K t ×σ a ) 1.5 −c 2 σ 2 m ]/K t where σ a and σ m are the normal stress amplitude and mean normal stress respectively on the plane of maximum range of shear stress, c 1 and c 2 are defined material constants and K t is the theoretical stress concentration factor.sp.info The effect of stress concentration on bone remodeling The effect of stress concentration on bone remodeling:theoretical predictions.

sized stress concentration rapidly fades away from the surface. It is still significant for promoting cyclic slip and crack nucleation at the material surface. Since fatigue cracks generally initiate on the specimen surface, it is well known that the surface roughness of a specimen has a great effect sp.info stress concentration - MechanicalStuff4uSTRESS CONCENTRATION When abrupt changes occur in any section of a machine part due to the presence of shapes like holes, grooves, keyways, threads etc., then localized high stresses occur in that section and also in the fibers nearest to that section.sp.info Interacting stress concentration factors and their effect Department:Mechanical and Aerospace Engineering Recommended Citation Whitley, David Warren, "Interacting stress concentration factors and their effect on fatigue of metallic The interaction of stress concentration effects between a hole and step are not well understood and the resulting impact on fatigue performance is difficult to predict sp.info The effects of embalming using a 4% formalin solution on This study aimed to determine the short- and long-term effects of embalming, using a solution with 4% formalin concentration, on the mechanical properties of human cortical bone. METHODS:Three-millimetre cylindrical specimens of human cortical bone were extracted from two femoral diaphyses and divided in four groups.

However, it seems to be difficult to locate a work that quantifies the rotation effect of polygonal cut-outs on stress concentration. Therefore, this study mainly focuses on stress concentration analyses of aluminium plates according to cut-out orientation.sp.info Surface Effect on Diffractions of Elastic Waves and Stress The dynamic stress concentration around the holes is calculated to illustrate the effect of surface effects on the multiple scattering of P- and SV-waves. We consider the multiple scattering of elastic waves (P-wave and SV-wave) by a cluster of nanosized cylindrical holes arranged as quadrate shape.sp.info Effects of Crystal Orientation on Stress Distribution Near The mechanical properties of intermetallic γ-TiAlbased materials depend strongly on the microstructure. The crystallographic finite element results show that the stress distribution near the grain boundary and triple junctions is very complex. This stress concentration depends on grain orientation and its stiffness matrix of neighboring grains.
