Tip cross-sectional geometry predicts the penetration depth of stone-tipped projectiles
Scientific Reports, 2020 Understanding prehistoric projectile weaponry performance is fundamental to unraveling past humans’ survival and the evolution of technology. One important debate involves how deeply stone-tipped projectiles penetrate a target.

Magnetic penetration depth and T_{c} in superconducting nickelates
Physical Review Research, 2020 We compute the nominal magnetic penetration depth of RNiO_{2} (R=La, Nd) from first-principles calculations and discuss the results in relation to the superconducting T_{c}.

Hybrid layer difference between sixth and seventh generation bonding agent
Dental Journal, 2006 Since etching is completed at the same stage as priming and bonding, when applying the sixth and seventh generation bonding, the exposed smear layers are constantly surrounded by primer and bonding and cannot collapse.

Generalized penetration depth computation [PDF]
Proceedings of the 2006 ACM symposium on Solid and physical modeling, 2006 Penetration depth (PD) is a distance measure that is used to describe the extent of overlap between two intersecting objects. Most of the prior work in PD computation has been restricted to translationalPD, which is defined as the minimal translational motion that one of the overlapping objects must undergo in order to make the two objects disjoint.

Numerical simulation of submarine pipeline penetration in sandy seabed
Journal of Hebei University of Science and Technology, 2022 In order to predict the penetration depth of submarine pipeline on sandy seabed,a coupled Eulerian-Lagranginan finite element model of submarine pipeline penetration on sandy seabed was established under ABAQUS to simulate the process of submarine ...

Melt Pool and Keyhole Behavior Analysis for Deep Penetration Laser Welding [PDF]
, 2010 One usually defines the main characteristic of the welding performances of a given laser system by its “penetration curve” that corresponds to the welding depth as a function of the welding speed Vw for a given set of operating parameters.

Penetration of a glass-faced transparent elastomeric resin by a lead-antimony-cored bullet [PDF]
, 2008 The penetration of the lead antimony-cored 7.62 mm × 51 mm bullet into a glass- faced polyurethane elastomeric polymer resin has been studied. The resulting craters in the resin contained elongated bullet core material that had a significant amount of ...

Soil Density in Traditional Mouldboard Tillage
Acta Technologica Agriculturae, 2023 Until recently, mouldboard ploughing was used as the main tillage in almost the entire territory of Ukraine and Russia. However, mouldboard technologies contribute to the formation of a “plough pan”, which contributes to additional soil compaction.
