In the second article, the structural response of bottom panels to slamming loads is investigated further. Experiments are described and results presented for modal and static analysis of the Numerette bottom panels in free air. Strain data is then presented from slamming experiments, investigating the influence of wave encounter conditions and vessel rigid body motions on response in the time and frequency domains.

This report presents the results of drop tests of 1/4-scale structural models with 10-deg deadrise angles. These models represented a portion of the ship bottom structure of a United States Coast Guard vessel. The test results were analyzed and correlated with results predicted by the theory discussed in referenced reports. Points of importance revealed by the study and summarized in the report include the nature of slamming loads, the dynamic interaction, the nature of underwater impact pressure, the structural damage phenomenon, the effect of repeated loads, and the effectiveness of adding damping material to the structure.

The report presents the results of an investigation on ship slamming through the use of drop tests of a rectangular elastic plate having two opposite edges hinged and two other edges free. The test program was conducted to verify use of the theoretical methods proposed in an earlier report for the solution of elastic response of a ship bottom to slamming loads. The report provides the theoretical solutions for a rectangular elastic plate, using the mathematical approximations, and then compares the solutions with the experimental data obtained from an actual drop test.

In rough seas a ship can be subjected to tremendous loads due to hydrodynamic impact, or slamming, whereby a high pressure pulse forms on the hull as it hits the water. The Lehigh University Composites Lab has been constructing a boat that will serve as a slamming load test facility to better understand this phenomenon. To quantify these slamming events sensors and a data acquisition system were needed that could both characterize the pressure pulse and the effect of the impact on the boat's structure. The present research details the development, construction and testing of a novel system that measures pressure and strain at high speed from hundreds of locations throughout the boat. Thin film sensors that adhere to the exterior of the boat hull were developed and tested in real world conditions. Hardware was fabricated to log from the instruments in the harsh environment of the slamming load test facility. This system uses off the shelf and custom electronics to record over 15 million samples of data per second. This hardware was installed in the test facility along with a user interface mounted in the rear seat of the cockpit to allow an operator to control measurement while the boat is undergoing tests.

This book describes a slamming strength assessment procedure for vessels. Typically, there are three types of slamming loads on commercial vessels: bottom slamming, bow flare slamming, and stern slamming depending upon the hull geometry at the bow and stern. Upon verifying compliance with the requirements in this book, optional notations may be assigned to the vessel. A fundamental requirement of Class is that the scantlings of the hull structure are to be in accordance with the criteria as specified by Class. The results of this book are therefore not to be used to reduce the basic scantlings obtained from the application of the Class rules. That is, if the results from this book indicate the need to increase any basic scantlings, the increased scantlings are to be implemented above the Class Rule requirements. In particular, this book shows the following features: Can be applied to ocean-going vessels including oil carriers, bulk carriers, container carriers, and gas carriers Describes the basic principles and requirements in the Classification Vessel Rules Written by an experienced lecturer
