Book excerpt: Benet Laboratories has the responsibility for safe fatigue life (durability) testing of cannon system components. This safe fatigue or service life evaluation is accomplished by conducting constant amplitude fatigue testing in a laboratory setting. One such cannon component that requires testing is the gun tube. After each tube has received the required number of live fire rounds necessary to generate initial cracking at the bore surface (also known as heat-check cracking), it is brought to the laboratory for final hydraulic fatigue testing. A sample size of two 155-mm M776 gun tubes was hydraulically fatigue tested to failure at Benet Laboratories to assist in determining the safe fatigue life for the weapon. This report contains the results of the fatigue tests conducted on the subject tubes, including material inspections, failure lives, and the resulting value for safe fatigue life of the XM776 gun tube.

Book excerpt: Benet Laboratories has the responsibility for safe service life (fatigue) testing of cannon system components. This safe service life evaluation is accomplished by conducting constant amplitude fatigue tests using hydraulic oil as the pressurized medium, One such cannon component that requires testing is the gun tube. After each tube has received the required number of live fire rounds necessary to generate heat check cracking in the bore, it is brought to the laboratory for final hydraulic fatigue testing. A sample size of seven 155- mm M284 gun tubes was hydraulically fatigue tested to failure at Benet Laboratories to determine the safe service life for the weapon. This report contains the results of the fatigue tests conducted on the subject tubes, including material inspections, failure lives, and the resulting safe service life.
Book Synopsis Fatigue Life Measurements and Analysis for Overstrained Tubes with Evacuator Holes by :
Download or read book Fatigue Life Measurements and Analysis for Overstrained Tubes with Evacuator Holes written by and published by . This book was released on 1995 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sections of cannon tubes with inner radius of 53, 60, and 78 mm were cycled from near zero to 100 to 300 MPa internal pressure until fatigue failure occurred. The failure locations were along 2-mm holes cut through the cannon wall at a 30 deg angle to the tube axis, for the purpose of evacuating combustion gases from the cannon after firing. The cannons had various amount of autofrettage by overstraining including 0, 30, 50, and 100 percent. The amount of overstrain affected both the initiation position of the fatigue crack along the evacuator hole and the measured fatigue life. Increasing the amount of overstrain moved the crack initiation from the tube inner radius toward a mid- wall position and significantly increased fatigue life. Fracture mechanics and solid mechanics-based calculations of fatigue life were performed for comparison with the measured lives. The calculations gave a good description of the measured life, taking account of tube configuration, applied pressure, amount of overstrain, stress concentration of the hole. Crack size and shape, material fatigue crack rate behavior and yield strength, and pressure in the hole and on the crack surfaces. As with measured fatigue life, the calculated life was significantly affected by the amount of autofrettage of the tube. The ratio of outer-to-inner radius of the tube and the presence of pressure in the evacuator hole also had substantial effects on the calculated fatigue life. (MM).

Available in PDF, EPUB and Kindle. Book excerpt: Training Circular (TC) 3-09.81, "Field Artillery Manual Cannon Gunnery," sets forth the doctrine pertaining to the employment of artillery fires. It explains all aspects of the manual cannon gunnery problem and presents a practical application of the science of ballistics. It includes step-by-step instructions for manually solving the gunnery problem which can be applied within the framework of decisive action or unified land operations. It is applicable to any Army personnel at the battalion or battery responsible to delivered field artillery fires. The principal audience for ATP 3-09.42 is all members of the Profession of Arms. This includes field artillery Soldiers and combined arms chain of command field and company grade officers, middle-grade and senior noncommissioned officers (NCO), and battalion and squadron command groups and staffs. This manual also provides guidance for division and corps leaders and staffs in training for and employment of the BCT in decisive action. This publication may also be used by other Army organizations to assist in their planning for support of battalions. This manual builds on the collective knowledge and experience gained through recent operations, numerous exercises, and the deliberate process of informed reasoning. It is rooted in time-tested principles and fundamentals, while accommodating new technologies and diverse threats to national security.

Download or read book Training Units and Developing Leaders (ADRP 7-0) written by Department Army and published by CreateSpace. This book was released on 2012-11-16 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Army Doctrine Reference Publication (ADRP) 7-0, Training Units and Developing Leaders, augments fundamental principles discussed in Army Doctrine Publication (ADP) 7-0, Training Units and Developing Leaders. Both ADP 7-0 and ADRP 7-0 support the doctrine established in ADP 3-0 and ADRP 3-0. Army units will face a complex operational environment shaped by a wide range of threats, allies, and populations. Rapid advances in communications, weapons, transportation, information technologies, and space-based capabilities make it a challenge to just stay even with the pace of change. Because Army units face a wide mix of challenges-from strategic to tactical-they must develop leaders to conduct unified land operations anywhere in the world in any operation across the conflict continuum. Army training prepares units and leaders to be successful through challenging, realistic, and relevant unit training and leader development at home station, at the combat training centers, and in the schoolhouses.
Book Synopsis Harappan Archaeology by : Shereen Ratnagar
Download or read book Harappan Archaeology written by Shereen Ratnagar and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book approaches the archaeology of the Harappan culture of Pakistan and India from the view point of the early state. It attempts to tease out information on the mobilization of labour, the organization of production,the direction of overseas trade by a newly formed elite, and the management of scarce water resources by the rulers. It discusses the environment and productivity of the culture, the sequence of excavations, early ideas of the civilization as quintessentially Indian, evidence for warfare and the hand of the state behind certainkinds of settlement morphology and artefactual equipment. It asks whether the residents of Mohenjo-darolived in kin-group clusters, and attempts to explain, through cross-cultural analogy, why the citadel sites arelocated where they are. A new idea on sailing routes is tentatively suggested, and it is argued that it was eliteintervention and management that secured both floodwater supplies at Dholavira and some degree of urbansanitation at Mohenjo-daro. Multiple views of the reasons for the end of the civilization are discussed in thefinal section of the book.
