Sonar domes, with stiffeners, house acoustic transducer arrays that are used to determine the direction of arrival of nearly plane acoustic waves generated by distant sources. Scattering of the waves, by the stiffener, disturbs the pressure field and causes a difference between the actual and measured directions of arrival. The errors, when using energy and split beam correlation methods, in fi...

Vertical load was applied uniformly over the entire top surface of the plate, and the load was increased in increments. For each load increment, the equilibrium state of the problem was determined. Because of the continuously hardening postyield behavior of Titanium Grade 7, equilibrium could be achieved for any vertical load. However, at a certain load level, the region of the plate between th...
