4.2.108 Contact_ratio

A Contact_ratio is the measure of the quality of contact of a shape on a reference surface. It is expressed as the ratio between the measure of the area of contact and the measure of the area of the reference surface.

A Contact_ratio is a type of Surface_condition.

The data associated with a Contact_ratio are the following:

4.2.108.1 measuring_gauge

The measuring_gauge specifies a Physical_model that serves as the reference for the determination of a Contact_ratio.

See contact_ratio to physical_model for the application assertion.

4.2.108.2 ratio_value

The ratio_value specifies a value between 0.0 and 1.0 that is the ratio between the measure of the area of contact and the measure of the area of the reference surface.

See contact_ratio to value_with_unit for the application assertion.
