Uniaxial tension, material sensitivity (aluminum)
StaticPASS · 0.64%Same geometry and load as the steel uniaxial tension case, aluminum instead of steel (E = 70 GPa) — verifies that the elastic modulus is correctly propagated to displacement (elongation scales as 1/E) while stress stays independent of the material in this statically determinate loading.Same geometry and load as the steel uniaxial tension case, aluminum instead of steel (E = 70 GPa) — verifies that the elastic modulus is correctly propagated to displacement (elongation scales as 1/E) while stress stays independent of the material in this stat… show full text

Problem statement
- Geometry
- Prismatic bar, 6.0 × 1.0 × 1.0 m.
- Material
- Aluminum: E = 70 GPa, ν = 0.33.
- Boundary conditions
- Fully fixed (all 3 DOF) on the x=0 face; uniform axial traction of +1 MPa on the x=6 face; lateral faces free.
- Measured quantity
- Displacement magnitude (elongation) at the free end (x=6). A secondary von Mises check at mid-span confirmed stress stayed at the same 1 MPa target as the steel case (0.00% deviation) — a statically determinate bar's stress does not depend on E, only on load/area.
