Unformatted text preview: der to ensure constant axial strain (implied by the "long" cylinder definition), nodal coupling is used with PLANE42 and SOLID45. Extra shapes are suppressed for PLANE42 and SOLID45. To illustrate the use of surface effect elements, the internal pressure P is applied using 2-D structural surface effect elements (SURF153) in the first analysis, whereas 3-D structural surface effect elements (SURF154) are used in the second analysis. Results are obtained from the solution phase and from the element centroid data.
