Rebounds of deformed cavitation bubbles
, 2018 Presented here are experiments clarifying how the deformation of cavitation bubbles affects their rebound. Rebound bubbles carry the remaining energy of a bubble following its initial collapse, which dissipates energy mainly through shock waves, jets ...

European Journal of Engineering Research and Science, 2020 A comparative analysis between Rebound Hammer and Pullout method in testing concrete was conducted in this study. Experimental analysis were carried out to compare the correctness between the two testing method in estimating the strength of concrete. Different cube (cubes of 175 x 175 x 175) samples were prepared using two mix designs of 1:2:4 and 1:3 ...

Development of rating curves for concrete rebound hammer on concrete specimens from local aggregates [PDF]
, 1957 Frequently engineers find it imperative to determine the compressive strength of concrete as it exists in a structure. There are two methods of making this determination, either by a destructive or a non-destructive test.

Predicting Concrete Compressive Strength and Modulus of Rupture Using Different NDT Techniques
Advances in Materials Science and Engineering, 2014 Quality tests applied to hydraulic concrete such as compressive, tension, and bending strength are used to guarantee proper characteristics of materials. All these assessments are performed by destructive tests (DTs).

Drop Splashing on a Dry Smooth Surface
, 2005 The corona splash due to the impact of a liquid drop on a smooth dry substrate is investigated with high speed photography. A striking phenomenon is observed: splashing can be completely suppressed by decreasing the pressure of the surrounding gas.
