WebUltrasonic Measuring Principle of Residual Stress in Curved Surface Components The main basis for the ultrasonic measurement of stress is the acoustic elasticity theory, that is, the stress state in the elastic solid will affect the propagation speed of the ultrasonic wave in a material [ 11, 12 ]. WebThe pressure force on the surface is equal to d F = P × d S = ½ × P × D × L × dθ The ( y, z) plane is a plane of reflection symmetry, so the x compound of this force is annihilated by the force on the symmetrical surface element. The y compound of this force is equal to: d Fy = cos (θ) d F = ½ × cos (θ) × P × D × L × dθ.

WebNote that Eq. 4.10 gives the normal stress in a curved member that is in the direction of the circumference (a.k.a. circumferential stress) and is nonlinearly distributed across the cross section (see Fig 4.3). It is worth noting that due to the curvature of the beam a compressive radial stress (acting in the direction of r) will also be developed. WebLikewise, stress tends to pile up on the inside and less on the outside of the curved link. Sharp Corners. Because of the curvature higher stress is going to be piled up on the inside surface so you will need to first be aware of unwanted stress concentrations due to sharp corners. Always use a radius where possible to minimize this effect.
