- An elastic body automatically restores itself after deformation.
- An elastic body tends to return to its original shape and size as soon as the deformating force is removed.
- In this thesis we investigate the net pressure load on an elastic body that is immersed in an inviscid fluid and undergoes compound vibration motion.
- Elastic statics mainly relates to the connection between force and transmogrification, elastic body's invalidation, the guide line of design in invalidation.
- The fingertip force sensor is the key for the complex task of the dexterous underwater hand,so a fingertip force sensor based on cylinder elastic body is developed.
