Cracking Assessment of Reinforced Concrete Slab Using Impact Hammer Test

Journal of Structural Monitoring and Built Environment
Impact hammer test is a vibration-based monitoring method used to detect cracking or damage in concrete structures by observing the vibration behavior such as the natural frequency, mode shapes and damping ratio. Damage or cracks in the structure can cause structure failure.

Hot Spot Formation in Mock Materials in Impact Sensitivity Testing by Drop Hammer

Propellants, Explosives, Pyrotechnics, 2017
AbstractPowder and granulated sugars were exposed to the drop hammer impact test configured with 120‐ and 180‐grit Si/C sandpapers. The sugars were selected as mock materials for HMX (Octahydro‐1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocine). The drop heights ranged from 24.2 to 40.7 cm.

Design of the angle hammers impact test system of the automobile fuel tank

2009 International Conference on Mechatronics and Automation, 2009
This paper introduces the design method of the angle hammers impact test system of the automobile fuel tank in detail. We have discovered the appropriate algorithm and have achieved the request precision through the computation of the data. We used the single chip of ATmega8 and a series of electronic elements to complete the control of the impact test

Advanced Hammer Excitation Technique for Impact Modal Testing on Lightweight Materials Using Scalable Automatic Modal Hammer

Experimental Modal Analysis (EMA) on a lightweight material has proven to be very challenging in the recent past. The applications of these materials have increased invariably in various fields and so have a high demand for Research & Development (R&D). A lightweight material is very sensitive in terms of vibration.
