Studies from Technical University Update Current Data on Optoelectronics (Measuring elastic flexural properties on marble slabs by a LDV system)

August 6, 2014

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Current study results on Optoelectronics have been published. According to news reporting out of Munich, Germany, by VerticalNews editors, the research stated, "Quality control of individual marble slab used for construction purposes prior to their application allows an effective reduction of security- and cost-relevant mechanical failures. Therefore, a non-destructive determination of flexural moduli of elasticity by consideration of marble's anisotropic behaviour is necessary."

Our news journalists obtained a quote from the research from Technical University, "Today's relevant standardized measurement systems allow a reliable determination of such moduli exclusively on specimens with other geometries than slab shapes. A measurement system with a Laser Doppler Vibrometer (LDV) operating in accordance with an eigenfrequency method is introduced in this paper. This system is designed for automatic quality control environments and provides for fast and non-destructive determination of a reliable value range of flexural moduli with respect to a multitude of marble varieties."

According to the news editors, the research concluded: "Results and advantages of the system are compared and discussed respectively to a frequently-used standardized ultrasonic measurement system."
