β¦ Synopsis
The quasistatic contact fracture under the action of a hard hemisphere striker impacting against a brittle halfspace is studied. For the quantities of most interest. the analytical expressions tested experimentally are obtained. The linear fracture mechanics concept is utilized. '06 G. P. CHEKEPANOV and V. B. SOKOLINSKY [IS] V. I. Mossakovsky and M. T. Rybka. An endeavour of construction -a brittle materials strength theory based on GriIXtb's energy considerations.

A fracture-mechanical theory for thermal stress fracture analysis of brittle bodies subjected to thermal shocks is presented. Criteria of crack instability for brittle solids under general thermal stresses are derived. Flaws in the form of circular Griffith microcracks are assumed to be distribute a
In an earlier publication (Engng Fractive Me& 32,249-258 (1989)) a stochastic fracture criterion was derived for a brittle body with population of crack-like defects under abritrary triaxial load. In this work the above criterion was applied to a nonuniform distribution of defect orientations, whose
Ah&ad-The enhanced strength observed for bodies under dynamic loading has been attributed to fracturing duration, i.e. the time interval between the commencement of fracture at the most heavily loaded point of the body and the instant of completion of fracture which is recorded by a sensor. The "dyn
