5. Tips & Best Practices

| Tip | Reason | |-----|--------| | Pre‑define multiple possible crack lines | If you are unsure where the crack will open, place several candidate joints and assign a low normal stiffness (e.g., 10 kN/m³). The one experiencing the highest tensile stress will open first. | | Use a “soft” normal stiffness instead of exactly zero when the solver struggles with convergence. | A tiny residual stiffness (1–10 kN/m³) stabilises the linear system while still allowing realistic opening (> mm). | | Check element aspect ratios – Keep the height/width ratio of elements adjacent to the crack ≤ 5. | Poor aspect ratios amplify numerical artefacts near the discontinuity. | | Validate against a simple analytical solution (e.g., a cantilever beam with a crack). | Guarantees that your joint properties are correctly defined before tackling complex geometry. | | Leverage the Phase‑Field module for verification – Run a quick phase‑field simulation of the same geometry. | If both approaches predict a similar crack path, you have confidence in the line‑element model. | | Document the joint parameters – Keep a small table (in your report) of kn, ks, φ, c, and cut‑off for every joint. | Makes model review and future updates straightforward. | | Avoid “over‑refining” – Excessive mesh density can cause extremely small time steps and long run times. Use adaptive refinement only where needed. | | Use the “Joint Slip” result type to evaluate whether the crack is sliding or just opening. | Helps decide if you need to increase φ or add cohesion. | | | Use a “soft” normal stiffness instead

When a line element (or a set of line elements) is assigned these properties, Plaxis treats it as a potential crack that can open fully once the tensile stress surpasses the cut‑off.
