Contact mechanics - Wikipedia
Hertzian contact stress forms the foundation for the equations for load bearing capabilities and fatigue life in bearings, gears, and any other bodies where two surfaces are in contact. History [ edit] When a sphere is pressed against an elastic material, the contact area increases. Zobacz więcej Contact mechanics is the study of the deformation of solids that touch each other at one or more points. A central distinction in contact mechanics is between stresses acting perpendicular to the contacting bodies' … Zobacz więcej The classical theory of contact focused primarily on non-adhesive contact where no tension force is allowed to occur within the contact area, i.e., contacting bodies can be … Zobacz więcej When two solid surfaces are brought into close proximity, they experience attractive van der Waals forces. Bradley's van der Waals model provides a means of calculating the … Zobacz więcej Classical contact mechanics is most notably associated with Heinrich Hertz. In 1882, Hertz solved the contact problem of two elastic bodies with curved surfaces. This still … Zobacz więcej The theory of contact between elastic bodies can be used to find contact areas and indentation depths for simple geometries. … Zobacz więcej When two bodies with rough surfaces are pressed against each other, the true contact area formed between the two bodies, $${\displaystyle A}$$, is much smaller than … Zobacz więcej • Adhesive – Non-metallic material used to bond various materials together • Adhesive bonding – Joining technique used in manufacture and repair Zobacz więcej WitrynaEquation 4: The maximum shear stress in any of the two spheres can be determined from: Equation 5: The relative displacement of the centres of the spheres … WitrynaThe Hertz theory equation assumes an elliptic stress distribution σ o = { ( W ( 1 + r p1 / r p2 ) )/ ( r p1 F π [ ( 1 - v 12 ) / E 1 + ( 1 - v 22 ) / E 2 ] sinφ )} 0.5 Where: σ o = Maximum value of contact stress (N/mm 2) W = force pressing the two gear teeth together (N) r p1 & r p2 = Pitch radii of the pinion and gear (mm) marinade for barbecue chicken legs
