Linear elastic stress
Small-strain, linear-elastic verification problems: analytic stress fields and stress-concentration factors compared against textbook references and body-fitted Abaqus simulations, with \(h/p\) convergence under mesh refinement.
Verification studies
The badge on each card identifies the study’s current release level.
Production
Prescribed displacement of a unit cube
Verify standard zero and nonzero face-displacement conditions, maximally smooth linear, quadratic, and cubic bases, multi-point probes, and output-database surface results on a minimal immersed solid.
Production
Stress concentration in a thin plate with hole
Verify the stress concentration at a circular hole in a coupon under uniaxial tension.
Production
Cantilever beam bending
Verify Abaqus gravity, body force, pressure, traction, and end-moment loading against Euler–Bernoulli closed forms using trimmed solid discretizations.
Production
Cantilever bimetallic beam bending
Verify a two-material solid against transformed-section solutions while exercising merged-part and tie-constraint interfaces.
Production
Multi-planar material interfaces
Verify that retained interface faces, edges, corners, and three-material junctions leave a homogeneous beam’s response invariant.
Production
Thick-walled spherical pressure vessel
Compare a curved trimmed solid under internal pressure with the exact Lamé solution and a body-fitted Abaqus reference.
