Publisher Description
This application helps to calculate peak stress when component is subjected to various loading conditions considering stress concentration factors due to discontinuities such as notches, holes and fillets. Stress analysis calculations assume that the components are smooth, have a uniform section and no irregularities. In practice virtually all engineering components have to have changes in section and / or shape. Common examples are shoulders on shafts, oil holes, key ways and screw threads. Any discontinuity changes the stress distribution in the vicinity of the discontinuity, so that the basic stress analysis equations no longer apply. Such 'discontinuities' or 'stress raisers' cause local increase of stress referred to as 'stress concentration'. The 'theoretical' or 'geometric' stress concentration factor Kt is used to relate the actual maximum stress at the discontinuity to the nominal stress. This application helps to calculate peak stress when component s subjected to various loading conditions considering stress concentration factors due to discontinuities such as notches, holes and fillets. Along with stress concentration factors, this app calculates the nominal and peak stresses, shares results via email with a couple of taps.
