History

Which material failure risk increases when winter temperatures drop within Mughal-era pietra dura inlays?

A)Adhesive bond fatigue
B)Mortar stress corrosion
C)Inlay differential expansion
D)Foundation heaving fracture

💡 Explanation

Internal cracking increases because differential thermal expansion occurs between materials with different coefficients, rather than uniform cooling. Therefore, inlays experience elevated stress concentrations along contact boundaries, rather than other failures due to bulk stresses.
