History

Which mechanical failure arises due to seasonal thermal expansion within the pietra dura inlay panels in monumental Mughal garden structures?

A)Adhesive bond delamination
B)Inert gas effervescence
C)Sacrificial anode depletion
D)Capillary action inhibition

💡 Explanation

Adhesive bond delamination results from differential expansion because the marble substrate and pietra dura components possess dissimilar thermal expansion coefficients, therefore seasonal temperature changes cause shear stresses at the adhesive interface, rather than uniform expansion.
