Problem statement

Geometry: Two prismatic blocks in uniform compression: A=100 mm2, h1=20 mm, E1=1000 MPa, h2=30 mm, E2=2000 MPa, nu1=nu2=0, P=100 N.
Material: Constitutive or analytical definition: p=P/A; delta=P(h1/(E1 A)+h2/(E2 A)).
Boundary conditions: Required solver capability: frictionless_contact. Use the loading/path control stated in the setup and preserve the complete response history.
Measured quantity: Uniform pressure=1 MPa, total shortening=0.035 mm, integrated contact reaction=100 N, tangential traction=0.
