Theory of Dynamic Strength

  • B. Steverding
Part of the Fracture Mechanics of Ceramics book series (FMOC, volume 1)


A whole series of problems related to stress wave-material interaction can be solved by using Fourier methods in connection with the recently discovered least action law for brittle fracture. A quantitative physical meaning will be given to the concepts of rest pulse, fracture potential, and penetration depth. A long and a short pulse of equal energy will be compared to show that the above quantities depend on the pulse length and the flaw distribution of the material. The concepts have a broad range of applicability and can be applied to problems in the areas of seismology, rock shattering, and impulsive processes of a military nature which up to now were impervious to quantitative analysis.
