Structural damage is based on the strength theory or the deformation theory, but in essence its main reason is that the stress in structures is larger than the strength of structural materials, or structural displacement and strain is larger than the capacity of structural material deform.
When the structural stress, strain (displacement) caused by blasting vibration is larger than the strength or deformation capacity of structural materials, structures would be damaged.
The structural damage caused by blasting vibration depends mainly on two aspects, one is the vibration characteristics of blasting vibration, namely, blasting vibration amplitude, frequency, duration, etc, another one is the dynamic response characteristics of the structure, which is related mainly to structural shapes, materials, terrain factors, etc.

In present model, once the temperature
field and solute field were solved by finite different method in the entire domain, the material
thermodynamic properties can be substituted into four algebraic equations to easily determine the
variation of solid fraction, interface temperature and solute concentration, instead of calculating
interface moving velocity.

As to polycrystalline materials, space charge polarization, ion vibration, electron polarization losses and deformation losses all happen in the frequency above GHz, so the dielectric loss tangent can be expressed as follows:
(2)
where εc" is the loss factor because of conductivity, εR" is the loss factor because of ion jump and dipole relaxation.
As known from formula (2), electrical conductivity loss is a key factor for many dielectric materials [17,25-27].

By fiber model, beams composed of composite materials, such as reinforced concrete beams, can be easily accounted for.
Because different fiber can have different material properties, we can use this method to account for offset problems [7], in which we can set the material properties of some fibers to be zero. 4.
Assuming small strains, the material model used for materially-nonlinear-only analysis can be directly employed in the Total Lagrange formulation for large displacement and large rotation analysis by simply substituting in the material characterization the second Piola-Kichhoff stresses and Green-Lagrange strains for the small displacement engineering stress and strain measures [5].

The sample material was made of an unspecified copper alloy.
Typical for these defects is that the moulding material remains baked in their vicinity.
This article was made possible by funding from the SGS‐2018‐051 project “Application of new treatment and test procedures to surfaces and bulk materials for improved usability of assemblies and work tools in industry”.
