Choosing the right level of verification
When a calculator is sufficient
Use property-focused calculations to establish a consistent baseline for material comparison, preliminary sizing and targeted verification. Always document material grade, processing state and the source of each property.
- For modulus and stress–strain checks, ensure that the measured response is in the appropriate elastic regime.
- For hardness conversion, confirm the reference material class and measurement scale; cross-scale values are approximate.
- For corrosion allowance, use a defensible service-environment rate rather than an unrelated handbook number.
- For thermal mismatch, distinguish free thermal expansion from deformation restrained by the assembly.
When to extend the analysis
Use test reports, relevant standards and specialist analysis when the material experiences complex loading or environmental degradation.
- Assess temperature, welds, heat treatment, texture, manufacturing history and material anisotropy where significant.
- Evaluate fatigue, fracture mechanics, creep, impact toughness and local yielding when these could govern failure.
- For corrosion, consider localized attack, galvanic couples, coating breakdown and nonconstant or uncertain corrosion rates.
- Check contact wear, polymer chemical compatibility and moisture effects using application-specific evidence instead of general material labels.
Common assumptions and mistakes
- Assuming hardness equals strength: Hardness can correlate with strength in certain material families, but is not a universal substitute for a certified strength property.
- Using room-temperature properties at operating temperature: Strength, modulus, expansion and corrosion behavior may change materially with temperature.
- Treating a uniform corrosion rate as complete life prediction: Pitting, crevice and galvanic mechanisms can dominate well before the predicted uniform-thinning life.
- Confusing hardenability with achievable hardness: Hardenability describes penetration of hardness through a section; it is not the same as maximum attainable surface hardness.
- Ignoring material condition: Cast, wrought, welded, tempered, aged and additively manufactured conditions can differ significantly.
Engineering questions
Frequently asked questions
What is the difference between Young’s modulus and yield strength?
Young’s modulus measures elastic stiffness: the slope of stress versus strain in the relevant elastic range. Yield strength marks the approximate onset of permanent deformation; it is not determined by modulus alone.
Can Brinell, Rockwell and Vickers hardness values be converted exactly?
No. Hardness conversions are empirical approximations and depend on material class and testing conditions. Use a directly measured value in the required scale for acceptance where necessary.
Does a corrosion allowance predict the lifetime of every metal part?
No. A rate-based estimate assumes a governing corrosion mechanism and progression model. Localized corrosion, changing environments and protective-system failure require separate assessment.
What is thermal-expansion mismatch stress?
When joined materials have different coefficients of thermal expansion and their relative movement is constrained, temperature changes can produce internal strain and stress. Actual interface compliance and geometry affect the result.
How is hardenability different from hardness?
Hardness describes resistance measured at a location; hardenability describes how deeply a steel can harden under specified heat-treatment and cooling conditions.
Can these calculators approve a material selection?
They support individual property and risk checks, not complete material qualification. Final selection requires traceable specifications, relevant service conditions, testing and applicable design requirements.
Can an Archard wear estimate predict wear life for every material pair?
No. The Archard calculation depends on a wear coefficient and load/sliding-distance assumptions appropriate to the specific tribological system. Its optional Hertz pressure screening is a separate simplified yielding check, not proof of wear performance.
What can the environmental stress cracking calculator conclude?
It evaluates matched no-crack test evidence against service stress and duration, or interpolates between two measured stress–failure points. It cannot establish environmental-stress-cracking resistance outside the relevance and range of the supplied experimental evidence.
