ST7-220.127.116.11 Plastic Beam Residual Stress
The Strand7 nonlinear material beam element uses either a moment-curvature table and axial stress-strain curve (R23x and prior) or a stress-strain curve only (R241 and later). To compare equivalent beam and shell models you must choose some analogous quantities. For stress, the beam fibre stress is analogous to the plate stress in the axial direction. The two cantilevered pipes are pushed past yield and subsequently relaxed to observe the resulting residual stress.
The extrapolated nodal...
