The membrane stresses are constant through the thickness Is the extreme fiber of the element in the positive local z direction,Īnd the “Bottom” is the extreme fiber of the element in the negative local , and σ xy values used to calculate the stresses are aĬombination of the plate bending and membrane stresses, thus the resultsĪre listed for the top and bottom surfaces of the element. Plate has a tensile yield stress of 36ksi, then a Von Mises stress ofģ6ksi or higher would indicate yielding of the material at some point Of ductile materials for design purposes. This stress can be compared to the tensile yield stress

Stresses and represents the maximum energy of distortion within theĮlement. The Von Mises stress is a combination of the principal Is ± π/4 radians from the principal stress directions. The direction of the maximum shear stress, t max, Is the angle in radians between the maximum normal stress and the local The Von Mises value is calculated using σ 1Īnd σ 2, but not σ 3 which isn't availableįor a surface (plate/shell) element, so this Von Mises stress does not include any transverse shear forces. The Angle entry is the angleīetween the element's local x-axis, and the direction of the σ 1 On the element at the geometric center of the plate. The principal stresses sigma1 (σ 1)Īnd sigma2 (σ 2) are the maximum and minimum normal stresses Selecting the Results Tab Envelope (or LC) button Plate Stresses. Alternatively, on the Results menu from the Explorer Panel you can select Plate Stresses Spreadsheet.
