Test No. LE1 The model is a thin plate of thickness 0.1m subjected to a uniform pressure for linear static analysis. OptiStruct examines the direct stress at the point on inside the ellipse on the x-axis.
Test No. LE2 OptiStruct examines the outer surface tangential stress at point E for linear static analysis.
Test No. LE3 The model is a hemispherical shell subjected to concentrated radial loads at its free edges. It examines the performance of the three-dimensional shell to model local bending behavior under conditions where the deformations are primarily due to bending.
Test No. LE5 OptiStruct examines the axial (x-x) stress (compression) at mid-surface, point A for linear static analysis.
Test No. LE6 OptiStruct examines the maximum principal stress on the lower surface at the plate center point E for linear static analysis.
Test No. LE10 The model is a thick plate subjected to uniform normal pressure of 1 MPa on the upper surface of the plate. OptiStruct examines the direct stress at the point D for linear static analysis.
Test No. LE11 The model is a thick solid cylinder subjected to linear temperature gradient in the radial and axial direction. OptiStruct examines the direct stress at the point A inside the cylinder on the y axis for linear static analysis.
A test of influence of offset on buckling solution for shells, including composite with offset Z0 and element offset ZOFFS.
