Sphere stress
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' surfaces (known as normal stress) and frictional stresses acting tangentially between the … Zobraziť viac 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-relevant classical solution provides a … Zobraziť viac The classical theory of contact focused primarily on non-adhesive contact where no tension force is allowed to occur within the contact area, … Zobraziť viac 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 tensile force between two rigid spheres with perfectly smooth surfaces. The … Zobraziť viac • [2]: More about contact stresses and the evolution of bearing stress equations can be found in this publication by NASA Glenn Research Center … Zobraziť viac The theory of contact between elastic bodies can be used to find contact areas and indentation depths for simple geometries. Some commonly used solutions are listed below. The theory used to compute these solutions is discussed later in the … Zobraziť viac 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 the apparent or nominal contact area $${\displaystyle A_{0}}$$.
