Abstract: Since World War II, periodic changes in the fabrication, design, and material specifications for ship steels have been made to preclude brittle fractures. These various changes are described ...

Abstract: Perlite is a volcanic aluminosilicate abundant in several countries that are major producers of portland cement. The amorphous nature and silica-to-alumina ratio of ground perlite indicate that it can be activated with ...

Abstract: Existing methods for evaluating spring steels in terms of load-loss resistance for automotive coil spring applications are very time-consuming and require special spring-making and spring-testing ...

Abstract: A general analytical method is presented for determination of the hydrodynamic entrance length of ducts of arbitrary cross section. Only knowledge of the fully developed velocity profile is ...

Abstract: The response to white noise excitation of a light elastic string loaded at equal intervals by a number of equal masses is examined using the theory of the Markov random process and the ...

Abstract: This paper deals with the vibration of heavy unsymmetrical shafts possessing unequal flexural rigidities in the principal directions and running in symmetrical bearings. The existence of several ...
