Load cases in the deck

Read straight out of the input file — geometry, orientation, boundary conditions and material all come from the deck, nothing is retyped. Tick the cases you want to run, then go to the Solver tab.

Boundary conditions

Mesh refinement

Choose meshes to run for every selected case. Specimen dimensions and applied displacements stay the same; constraints extend to the new face and edge nodes.

The choices contain 1, 8, 27, 64 and 125 elements. Finer meshes take longer to solve.

Material

Step controls

The model is invariant under a uniform scaling of time, so a shorter step runs faster and traces the same curve — as long as it stays quasi‑static. Watch the KE/SE column in the results: above about 1 % the answer is being driven by inertia, not the material.

Solver

Material card The deck card and the paper's Table A.1 disagree; see the README. NCF_corrected is the reconciled set. Step time (s) Output points Samples recorded per case. Hourglass coefficient Flanagan–Belytschko viscous stabilisation. 0 disables it. Courant safety factor Fraction of the stable increment actually used.

Compare in Abaqus or LS-DYNA

Download a ZIP with one job per selected case and mesh, using the material card and step controls above. You can export without running the internal solver.

LS-DYNA user-material library Path on your LS-DYNA machine to the compatible SHF UMAT43 library.

Abaqus includes the VUMAT source. DYNA requires your external user-material library. Each ZIP includes run and comparison instructions.

Stress, material strain, damage and the strength summary report the first element. Force curves sum reactions over the entire support face.

Energy columns read up to the peak / whole run. The first says whether the reported strength is the material's; the second whether the softening branch is.
