The multi-material rod below has force P=3 kN applied to it
The multi-material rod below has force P=3 kN applied to it. The center portion is steel, with E=207 GPa and yield strength Sy=250 MPa. The outer shell is aluminum with E=69 GPa and yield strength Sy=276 MPa. The center portion has cross-sectional area of 7.07 mm2 while the outer shell has cross-sectional area of 5.50 mm2 . The load P is applied through rigid plates (not pictured) so that the force is shared between the two materials. Note: This scenario is used...
