Human skin is a quasi-incompressible material.
That is why it is more difficult to press soft tissue than a sponge-like material.
The fixture made of a foam material was used to support and fix the palms.

Introduction Reactive powder concrete (RPC) is a new type of concrete material with ultra-high strength, high durability and good crack resistance, which has been widely used in construction and transportation fields [1-4].
Thus: (11) (12) (13) Substitute into Eq. 5 to get: When calculating the deflection of pole, it is assumed that the bottom of the pole for embedded and fixed cantilever beam, the deflection of pole mainly comes from the elasticity of the material itself and after contact with the soil compression deformation, produced by the prestressed RPC pole presumes that foundation stiffness is very big, when pole build-in sections are all fixed, horizontal forces will lead to structural materials elastic deformation, the deflection of the peak at this time as follows: Where: ∑P—resultant horizontal forces; H—he height from the top of the rod to the fixed point; B0—short-term stiffness of reinforced concrete soil flexural members calculated by quasi-permanent combination of loads or prestressed concrete
The material parameters of the calculation model (prestressing steel bar, ordinary steel bar, reactive powder concrete, stirrups) are taken from the experimental values, as shown in Table 1-2.
