← HistoryWhat consequence results when cyclical thermal stresses act upon marble 'Pietra Dura' inlay found in Mughal monuments?
A)Adhesive bond line cracking✓
B)Increased bioturbation rate
C)Decreased phonon scattering
D)Accelerated base metal oxidation
💡 Explanation
Differential thermal expansion between the various inlaid stones and the marble matrix induces cyclic stress, leading to adhesive bond line cracking because of fatigue failure. Therefore, the inlay degrades, rather than exhibiting altered phonon scattering or electrochemical reactions with the metal base.
