Physical damage

All physical damage begins on the

s, and the rate at which damage to any physical thing occurs is therefore largely dependent on the elasticity of such bonds in the material being subjected to stress. Damage can occur where atomic bonds are not completely broken, but are shifted to create unstable pockets of concentration and diffusion of the material, which are more susceptible to later breakage. The effect of outside forces on a material depends on the relative

of the material; if a material tends towards elasticity, then changes to its consistency are reversible, and it can bounce back from potential damage. However, if the material tends towards plasticity, then such changes are permanent, and each such change increases the possibility of a crack or fault appearing in the material. Although all damage at the atomic level manifests as broken atomic bonds, the manifestation of damage at the macroscopic level depends on the material, and can include cracks and
deformation Deformation can refer to: * Deformation (engineering), changes in an object's shape or form due to the application of a force or forces. ** Deformation (physics), such changes considered and analyzed as displacements of continuum bodies. * Defor ...

Damage to objects

Damage to structures and other objects can take a number of forms, such as

When an object or building is deliberately damaged, the act can be socially significant as a way to degrade the meaning of the object. Though things can have multiple meanings, in circumstances where they are deliberately damaged one meaning—which prompts the act—takes precedence.
