Title: Innovations of Leo M DeLangis

Introduction

Leo M DeLangis is a notable inventor based in Lomita, California. He has made significant contributions to the field of materials science, particularly in the measurement of mechanical properties of plate structures. With a total of six patents to his name, DeLangis has developed innovative methods and apparatuses that enhance the understanding of material stiffness.

Latest Patents

Among his latest patents is the "Apparatus for in-situ nondestructive measurement of Young's modulus of plate structures." This invention involves a method and apparatus for determining the stiffness of a plate-like structure, including monolithic or composite laminate plates. The process entails placing a device that generates an acoustical pulse against the surface of the plate and positioning a detecting device at a known distance from the pulse-generating device. By emitting a pulse to create an extensional wave in the plate, the detecting device measures the time of flight of the wave, allowing for the calculation of wave velocity. A processor then determines the Young's modulus of the plate based on this velocity. This patent also discloses methods and apparatus for evaluating both isotropic plates and anisotropic laminates.

Another significant patent is the "Method for in-situ nondestructive measurement of Young's modulus of plate structures." This method similarly involves generating an acoustical pulse and measuring the wave's time of flight to determine the stiffness of a composite laminate plate. It provides valuable insights into both anisotropic and quasi-isotropic laminates.
