WebFeb 9, 2024 · July 12, 2024 GMT. Shimadzu has released the MIV-X Ultrasonic Optical Flaw Detector. The MIV-X visualizes and digitizes flaws (peeling, cracks, and voids) in parts and multi-materials in aircraft, automobiles, and electrical and electronic equipment using our proprietary ultrasonic optical flaw detection technology, which acquires an image of ... The traditional approach to the design and analysis of a part is to use strength-of-materials concepts. In this case, the stresses due to applied loading are calculated. Failure is determined to occur once the applied stress exceeds the material's strength (either yield strength or ultimate strength, depending on the … See more In fracture mechanics, a stress intensity factor is calculated as a function of applied stress, crack size, and part geometry. Failure occurs once the stress intensity factor exceeds the … See more The theoretical value of stress at the tip of the ellipse is given by: where σ is the nominal stress and ρ is the radius of curvature of the ellipse, ρ=b2/a. where a is the crack size and Y is a dimensionless geometry factor that … See more Fracture mechanics is important to consider for several important reasons: Because the concept of the stress intensity factor assumes linear elastic material behavior, the stress intensity factor solutions can … See more As the radius of the crack tip approaches zero, the theoretical stress approaches infinity. This infinite stress is known as a stress singularity and is not physically possible. Instead, the … See more
