Artificial Neural Network Model for Prediction of Bearing Capacity of Driven Pile
Jurnal Teknik Sipil, 2015 This paper presents the development of ANN model for prediction of axial capacity of a driven pile based on Pile Driving Analyzer (PDA) test data. As many as 300 sets of high quality test data from dynamic load test performed at several construction ...

Ultrasonically Assisted Hammer-Action Penetrators in Planetary Regolith [PDF]
, 2018 This paper describes the effects of combining ultrasonic vibration with hammer-action style penetrators, such as the HP3 probe on the InSight mission. By synchronizing short pulses of vibration with the impact of the hammer, the number of hammer strikes ...

Comparative Shear Tests of Bolt Rods Under Static and Dynamic Loading
Studia Geotechnica et Mechanica, 2020 This article presents the methodology and results of single shear tests of bolt rods under dynamic impact loading generated by means of a drop hammer. Comparative analysis was also performed for bolt rod load capacity, stress and shear work under static ...

Estimation of Impact Hardness of Rocks by Means of Drop Hammer Test.
Shigen-to-Sozai, 1992 The impact hardness of rock is normally determined by using a ‘Protodyakonov’ type drop hammer. However, this test cannot be applied to a wide range of rocks. Therefore, standardized impact hardness test using the ‘Protodyakonov’ type drop hammer was carried out and the correlati ons of the resulting values of impact hardness with the mechanical ...
