Measuring the strength of brittle materials by depth-of-penetration testing [PDF]
Advances in Applied Ceramics, 2010 Based on an energy conservation model, the strength offered by a number of brittle materials has been calculated from depth-of-penetration (DOP) test results. Each material was completely penetrated by a tungsten carbide cored projectile of known kinetic

Effects of elastoplastic strengthening of gravel soil on rockfall impact force and penetration depth
, 2020Gravel soil backfilled on the top of a rock shed serves as a cushion and protects structures in mountainous districts that are endangered by rockfalls. Strengthening effect under rockfall impact is one of the factors that can influence the properties of ...

Penetration depth of a superconducting superlattice
Physical Review B, 1987We have measured the magnetic-flux expulsion of a superconducting superlattice and related it to the Meissner penetration depth. The temperature dependence of the penetration depth is in quantitative agreement with theoretical expectation based on mean-field theory.

Geometrical scaling effect for penetration depth of hard projectiles into concrete targets
International Journal of Impact Engineering, 2018Since penetration tests of concrete targets against rigid projectiles are commonly conducted in reduced geometrical scale, whether the replica scaling law holds or not is very important for extending the knowledge based on the small-scale experiments to ...

3D numerical investigation of the effect of wall penetration depth on excavations behavior in sand
Computers and geotechnics, 2018The present paper evaluates the effect of penetration depth of a diaphragm wall on the behavior of excavations in sandy soils using the finite difference method. A three-dimensional (3D) modeling is performed for excavation depths of 10 to 20 m.

Equations for depth of penetration of projectiles
Journal of the Royal Army Medical Corps, 2014Breeze et al [1][1] analysed experimental data on how far fragments penetrate into 20% gelatin and goat tissue. Theory may assist interpretation. Suppose force resisting movement through gelatin or tissue is proportional to a power function of instantaneous velocity w, that is, force ∝ wn ...
