Angles of friction and dilatancy of sand

critical state angle of almost 34-40 would have been reached on further straining. This angle is obtained from the loose sand data in Fig. 3, and is assumed here to be the critical state angle of friction. Having obtained a peak friction angle of 40-420 for the dense sand and a maximum friction angle of 34-40 for the loose sand, it is ...

Contact angle - kruss-scientific

The contact angle (wetting angle) is a measure of the wettability of a solid by a liquid. In the case of complete wetting (spreading), the contact angle is 0°. Between 0° and 90°, the solid is wettable and above 90° it is not wettable.
