The brachioradialis tendon is located: Proximal to the wrist.The associated theory of indentation method is presented and specialized to the particular case of the constitutive behaviors of skin so as to establish the theory basis of this work. The indentation tests are performed on the inner forearm in the relaxant and uniaxially pre-stretched state, respectively.Edema. This is the temporary cause of indentation from pressure. The dents may appear all over the body, including the face, back, thighs, legs, and abdomen. Edema makes the skin appear swollen due to the accumulation of fluids. When the swollen area is pressed, it forms dents. These dents, however, last for a short time.The human skin adhesive behaviour is investigated by varying different parameters; namely the normal load, the indentation speed, the contact time and the indenter geometry.
