A handheld tool for NDT Descriptions:Ultrasound Calc contains all calculations which are frequently required in industrial applications to NDT technicians of levels I and II.This application turns your smart phone in a powerful calculator which simplifies the complexity of ultrasonic formulas used to select a transducer or setup an inspection into friendly interactive screens. Ultrasound Calc allows to calculate the near field, beam divergence, convergent point; moreover for weld inspections, you can find defect position, stand off and depth. It also includes the incident angle calculation for inspection under immersion conditions.The application has a database of material properties to look up the longitudinal and shear wave velocity as well as impedance, density and wavelength for a given frequency Main features- References of constants and wavelength for more than 50 materials – Calculation of mean transducer parameters and transducer selection.- Snell
