The stress ﬁeld near the contact edge in JKR model has a crack-like singularity and the size of the contact region can be determined by the Grifﬁth energy equi-librium criterion, which is larger than the contact size predicted by Hertz theory.

Web20 uur geleden · Hollow microgels are fascinating model systems at the crossover between polymer vesicles, emulsions, and colloids as they deform, interpenetrate, and eventually shrink at higher volume fraction or when subjected to an external stress. Here, we introduce a system consisting of microgels with a micrometer-sized cavity enabling a … The JKR model considers the effect of contact pressure and adhesion only inside the area of contact. The general solution for the pressure distribution in the contact area in the JKR model is p ( r ) = p 0 ( 1 − r 2 a 2 ) 1 2 + p 0 ′ ( 1 − r 2 a 2 ) − 1 2 {\displaystyle p(r)=p_{0}\left(1-{\frac … Meer weergeven 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' … Meer weergeven 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 … Meer weergeven When two bodies with rough surfaces are pressed against each other, the true contact area formed between the two bodies, Meer weergeven • Adhesive – Non-metallic material used to bond various materials together • Adhesive bonding – Joining technique used in manufacture and repair • Adhesion railway – Railway which relies on adhesion traction to move a train Meer weergeven 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 foundation for modern problems in … Meer weergeven 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.
