Elastic rubber ball of viscoelastic base

Rubber is a kind of viscoelastic body, flexible, this also is all bouncy ball manufacturers choose it to make elastic ball causes, it specific what performance: It is typical of elastomer and steel under external force as, can produce instantaneous deformation, stress and strain are proportional, when external force to remove eliminated instantly, recovery after deformation original shape. The typical inviscid fluid under external force, then produce sustained deformation, stress and strain rate, when external force is proportional to the removal of deformation will continue to exist after, not disappear. The mechanical properties of rubber elastomers and sticky fluid between between so called the viscoelastic body, it is shown as strain increases over time, the creep phenomenon in fixed strain, it is shown as stress increases over time, reduced relaxation phenomenon, in alternating stress the role, it lags behind the stress, strain in external bouncy ball as under the action of change speed direction and deformation,
