| Finite Element Numerical Model for Deformation Energy of Structural Belts |
| The difference and distribution of inner_deformation energy in different structural belts under the same external force and boundary and lithomechanic character are studied by finite_element numerical model. Energy of shape changing (or distortional energy) U W is bigger almost a number level than energy of volume changing (or dilation energy) U T . U W and U T and structural deformation energy U B gradually decrease successfully in the compressive, shearing and extentional deformation belts. U W and U B roughly have a bigger→big→small distribution variation, and U T has a big→bigger→small trend variation. This law of structural deformation energy, in addition to the study on hydrostatic pressure derived from structure, is of important consult value to research the structural deformation heat and its impact on fluid migration. |
