Interface qualification
Will this joint, coating or barrier survive its duty cycle?
Give Surphysis the layer stack, the duty cycle and your own characterisation files. It returns the fracture margin, the breakthrough time and the survival probability, with the one measurement that would change the answer.
Free for academic labs. No AI at runtime: every number comes from a numbered physics rule you can audit.




Six industries. One question about the interface.
Every sector below has a duty cycle library built in, so a case starts from a real service condition, not a blank form.






Nineteen services, three doors
Design it, analyse what you built, qualify it for service
Each service is a chain of numbered rules. 10 are live today; the rest are in validation and open a request, never a dead end.

How it works
Four steps, one audit trail
The engine
Physics you can audit. No AI at runtime.
Twenty-five numbered rules cover thermo-elastic mismatch, minimax graded interlayers, grain-boundary diffusion, interface fracture mechanics and global sensitivity. Each rule cites its equation and its sources; each run prints the numbers it used.
- Continuum mechanics and fractureBiaxial mismatch stress, minimax step rule, Hutchinson and Suo energy release rates, mode-mixity toughness
- Microstructure and kineticsScherrer and Williamson-Hall grain size, Hart effective diffusivity, Harrison regimes, barrier breakthrough
- Uncertainty that ranks the next measurementMonte Carlo over stated error bars, Saltelli Sobol indices, measure-next by variance reduction per cost
R00 · preferred value selection
Stages left to right; every line is a dependency declared in the rule registry.
What a verdict reads like
One page. The weakest interface, its life, and what to measure next.
No score out of ten. A named interface, a named mechanism, a number with its band, and the assumption that most controls it. Written for the engineer who has to sign.

Conditional pass
| Weakest interface Chromium barrier, consumed by grain-boundary diffusion of Ni | 1 pulses |
| Survival over 5 pulses Monte Carlo, 4 000 draws | P = 0.01 |
| Interlayer step stress Minimax grading, 5 steps | 0.63 GPa · pass |

Why Surphysis
The tools you own stop at properties or at stress. The verdict lives in between.
Surphysis runs on top of the simulation and database tools you already have. It replaces the six-week consultancy report, not your stack.

Public scorecard
Every prediction is timestamped before the outcome is read. Hits and misses stay visible. The first campaign runs against published thermal barrier and hydrogen barrier failures.
Your data stays yours
Uploads are parsed in your browser. Nothing leaves your machine until you export a report. No model is trained on your files, because there is no model.
Built from the literature
Every property carries its source, method, form and temperature window. Disputed values stay disputed and widen the band rather than pick a side.
Request a demo session
Bring one interface you worry about. We run it live.
Forty minutes on a call. You describe the stack and the duty cycle, we run the case in front of you and hand you the verdict report afterwards. Academic labs get an account on the same call.
