← HistoryWhich consequence results when differing thermal expansion coefficients exist between marble substrates and pietra dura inlay in Mughal monuments?
A)Inlay detaches due to shear stress✓
B)Marble strength increases significantly
C)Inlay elements become more ductile
D)Substrate experiences isostatic recrystallization
💡 Explanation
Delamination occurs through differential expansion; this introduces shear at the marble/inlay interface because the *thermal stress concentration* accumulates, therefore the weaker adhesive bond fails, rather than changes in material properties
