摘要
The distinctive features of the healing of pores in copper (with an initial porosity of 12%) by various types of static and shock-wave-induced stresses are discussed. It is shown for static loading that the process of healing is determined by the maximum shear stress at the surface of a pore and the character of the distribution of shear stresses near the pore. The observed increase in the efficiency of healing of the porosity when dynamic methods of compression are used as compared to static methods is attributed to an increase in temperature due to local heating near the pore.
