Hertzian contact fatigue
WitrynaHertzian fatigue is caused by repeated contact stresses that cause surface or subsurface fatigue cracks and detachment of material fragments from gear … Hertzian contact stress refers to the localized stresses that develop as two curved surfaces come in contact and deform slightly under the imposed loads. This amount of deformation is dependent on the modulus of elasticity of the material in contact. 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 separated without adhesion forces. Several analytical and numerical approaches … Zobacz więcej When two solid surfaces are brought into close proximity, they experience attractive van der Waals forces. Bradley's van der Waals model … Zobacz więcej Classical contact mechanics is most notably associated with Heinrich Hertz. In 1882, Hertz solved the contact problem of two elastic … 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, Zobacz więcej • Adhesive – Non-metallic material used to bond various materials together • Adhesive bonding – Joining technique used in manufacture and repair Zobacz więcej
