Title

NUMERICAL ANALYSIS OF THE EFFECT OF STRUCTURAL DISCONTINUITIES ON BLAST- INDUCED WAVE PROPAGATION IN A PLEXIGLASS MEDIUM

Pages

  1-11

Abstract

 In this paper, the effect of structural discontinuities on blast- induced wave propagation in a PLEXIGLASS media is investigated by using UDEC Code which is a DISTINCT ELEMENT METHOD based. The stress wave resulting from the explosion of a cylindrical charge is simulated by a triangular pulse which is the result of a dynamic pressure equivalent to 11GPa. This pressure is applied to the blast hole wall with 5.08 mm diameter as a uniform load. Dynamic pressure on blast hole is considered to be radial and is distributed uniformly. Peak particle displacement, peak particle velocity, applied stress, reflection and transition coefficients are estimated for elastic media behavior. The obtained numerical results are compared against experimental results of Fordyce et al, (1993). A good agreement between numerical and experimental results is achieved.
