Unformatted text preview: E = 7200 psi µ = 0.33 σyp = 10 psi ET = 40 psi Geometric Properties R1 = 10 in R2 = 20 in Loading Θ = 60° At nodes on the inner surface in 10 equal load steps along the circumference Analysis Assumptions and Modeling Notes The problem is solved three times, each time with a different element type. The element types used are VISCO106 (2-D, 4-node viscoplastic element), VISCO108 (2-D, 8-node viscoplastic element), and VISCO107 (3-D, 8-node viscoplastic element), respectively. The plasticity is modeled using the bilinear isotropic hardening rule. ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–447 VM198 The plane strain condition is assumed along the length of the cylinder. Due to the axisymmetric loading, only a small portion (3° span) of the cross-section is modeled each time using ten elements. Nodal rotations and displacement couplings are employed to ensure the circumferential symmetry in the deformed configuration. To illustrate the dynamic substitution of a parameter value, an alphanumeric character parameter (element ty...
