In elastic stage, these two stresses must satisfy following equations α ττ G yx xz yz 2= ∂ ∂ − ∂ ∂ , 0= ∂ ∂ + ∂ ∂ yx yz xz ττ (1) where G is the shear module of the isotropic material; α is the torsion angle along the unit length of the bar. τxz and τyz can be expressed in terms of stress function Φe as ye xz ∂ Φ∂ =τ , xe yz ∂ Φ∂ −=τ (2) Substitution equation (2) into the first expression of equation (1) yields αG yx e e e 22 2 2 2 2 −=      ∂Φ∂ + ∂Φ∂ =Φ∇ (3) And the elastic torque Te can be evaluated by ∫∫ Φ= A e e dxdy T 2 (4) So, at this stage, once the stress function is obtained, the stresses and the torque can be determined.

Storage tanks play a critical role in various industries, including oil and gas, chemicals, food, and pharmaceuticals, by ensuring the safe and efficient storage of valuable and often hazardous materials.
The stress and the deformation of the tank were calculated, then the result was compared with the strength limit of the material.
The stress of the tank was calculated by finite element method, then the maximum stress was compared with the allowable stress of the material.
This stress was lower than the allowable stress of material which is 163 MPa.

The focus has been placed on how to reduce our waste release into air, water and soil, how to sand less materials to landfills while maintaining our living quality, how to improve the producing techniques so they deplete natural resources more slowly and produce fewer dangerous materials.
Cradle to Cradle Design recognizes two metabolisms within which materials flow as healthy nutrients: Biological Metabolism and Technical Metabolism.
Biological Metabolism: Materials that flow optimally through the biological metabolism are called biological nutrients (e.g. the nitrogen cycle).
As a world-wide leader in this industry, he confidently adopted all the scale, materials and process to rural Chinese villagers.
So he changed this materials flow and imposed his Cradle-to-Cradle circular economy to the local people.
