Contact mechanics is the study of the deformation of solids that touch each other at one or more points. [1] [2] 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 surfaces (shear stress).
Contact mechanics is the study of the deformation of solids that touch each other at one or more points. [1] [2] This can be divided into compressive and adhesive forces in the direction perpendicular to the interface, and frictional forces in the tangential direction.

In contact mechanics, the term unilateral contact, also called unilateral constraint, denotes a mechanical constraint which prevents penetration between two rigid/flexible bodies. Constraints of this kind are omnipresent in non-smooth multibody dynamics applications, such as granular flows, [ 1 ] legged robot , vehicle dynamics , particle ...
The microscopic origin of contact forces is diverse. Normal force is directly a result of Pauli exclusion principle and not a true force per se: Everyday objects do not actually touch each other; rather, contact forces are the result of the interactions of the electrons at or near the surfaces of the objects.

Sliding contact of solids (black) through a third medium (white) using the third medium contact method with HuHu-regularization. The third medium contact (TMC) is an implicit formulation used in contact mechanics. Contacting bodies are embedded in a highly compliant medium (the third medium), which becomes increasingly stiff under compression.
Contact transformations are related changes of coordinates, of importance in classical mechanics. See also Legendre transformation . Contact between manifolds is often studied in singularity theory , where the type of contact are classified, these include the A series ( A 0 : crossing, A 1 : tangent, A 2 : osculating, ...) and the umbilic or D ...
