Test No. FV2 A pin-ended double cross, in-plane vibration problem. OptiStruct is used to investigate the coupling between flexural and extensional behavior, as well as the repeated and closed eigenvalues of the double cross in Normal Modes Analysis.
Test No. FV4 The problem is set up to test the behavior of coupling between torsional and flexural, off-center inertial axis, and close eigenvalues. OptiStruct is used in this normal modes analysis.
Test No. FV5 OptiStruct tests the repeated eigenvalues, shear deformation, and rotary inertia. The possibility of missing extensional modes is also investigated.
Test No. FV12 A thin square plate model, which contains three rigid body modes. OptiStruct investigates the repeated eigenvalues and kinematically incomplete suppressions of the thin plate in Normal Modes Analysis.
Test No. FV15 The behavior of distorted thin elements in normal modes analysis is examined using OptiStruct.
Test No. FV16 A cantilevered thin square plate of 10m×10m dimension. OptiStruct is used to investigate the frequencies at different modes for different test cases.
Test No. FV22 The behavior of distorted, thick elements in normal modes analysis is examined using OptiStruct.
Test No. FV32 A tapered membrane problem with irregular mesh. The geometry and mesh symmetry are maintained along the x-direction. The shear behavior of membrane elements in the Normal Modes Analysis is examined using OptiStruct.
Test No. FV41 A free cylinder with axi-symmetric vibration. OptiStruct is used to investigate the rigid body mode, close eigenvalues, and the coupling between axial, radial and circumferential behavior.
Test No. FV52 A well-established solid square plate, which contains three rigid modes with the given boundary condition. The test examines the performance of OptiStruct Normal Modes Analysis on 3D solid elements.
A vertical clamped free cylindrical shell with a rigid bottom is chosen to demonstrate the applicability of the structures which are partially filled such as liquid storage tanks.
