An expression representing trajectories of fracture paths is obtained as a first arrival length. The first arrival length is a function representing a quantity generalized from the first passage time. The expression is the average value of the first arrival length found by solving a backward...
Hydraulic fracturing or hydraulic stimulation is one of the most effective methods of enhancing of the hot dry rock (HDR) geothermal system productivity. The 3D structure of the fractured rock is approximated with the network models of “fractal geometry”. The models of fracture networks are...
Fracture processes in concrete specimens were observed in mesolevel simulations. For generating the composite structure of the concrete in the three-dimensional space, a new stochastic-heuristic algorithm has been developed which allows obtaining specimens with comparably high aggregate contents...
This paper describes a new ultrasonic method for sensitive evaluation of surface connected small closed cracks of size ranging from 0.3 to 3.5 mm in steel plates. Ultrasonic echo obtained by shear wave (SW) beam of 50° incidence in material from the back-wall crack is used. First, the ultrasonic...
The stress concentration factor at the tip of central crack in a strip is evaluated in two steps of numerical analysis. In the first step, stress distribution around the small region, SR, which includes a crack-tip, is analyzed under a given tension. In the second step, the small region is...
Creep and crack growth properties of W strengthened high Cr steel weldment have been investigated at 923 K. Most of the joint specimens were type IV fractured in fine-grained HAZ and showed shorter creep lives than base metals. The relations of creep properties and precipitation and dislocation...
