How this service works
Estimate differential strain from supplied expansion coefficients and temperature changes. For preliminary scenarios; no stress, delamination or reliability certification. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.
Output
Returns the estimated differential strain (dimensionless or in strain units) arising from the mismatch between the two supplied thermal expansion coefficients over the given temperature change. This is a preliminary numerical estimate for screening purposes only; it does not include stress, delamination risk, or reliability certification.
Example use cases
Thin film on substrate screening
“I need to quickly check the differential strain between a copper film (CTE 17e-6 per K) and a silicon substrate (CTE 2.6e-6 per K) over a 150 K temperature change — just a preliminary public-data estimate to see if the pairing is worth pursuing.”
Semiconductor packaging compatibility
“Can you compute the thermal mismatch strain for a GaN-on-SiC layer stack? GaN has a CTE of about 5.6e-6 per K, SiC is about 4.0e-6 per K, and I'm looking at a delta T of 250 K. Use synthetic data class.”
PCB solder joint thermal cycle estimate
“What's the estimated differential strain between a FR4 board (CTE ~18e-6 per K) and a ceramic component (CTE ~7e-6 per K) across a 100 K thermal cycle? Flag it as public data for a feasibility screening.”

Endpoint
POSThttps://www.mahastrategies.com/api/v1/compute/materials/thermal-expansion-mismatch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, inexpensive preliminary numerical estimate of differential thermal strain between a thin film and a substrate during early design or material selection. It is ideal for screening CTE compatibility before committing to more detailed finite-element or reliability simulations. Not suitable for stress analysis, delamination prediction, or any reliability certification.
Side effects
- Missing required fields (alphaFilmPerK, alphaSubstratePerK, or deltaTemperatureK) return a validation error
- Values outside the allowed numeric range trigger a boundary error
- Invalid or missing dataClass enum value causes a request rejection
- Payment failure or insufficient USDC balance prevents call execution
- Server-side computation error returns a 5xx response
