← HistoryWhich outcome results when thermal expansion mismatch influences subsurface 'pietra dura' inlay placement within Mughal architecture?
A)Pattern fracturing and material delamination✓
B)Uniform thermal stress distribution occurs
C)Enhanced structural integrity over time
D)Increased colour vibrancy within pietra dura
💡 Explanation
Delamination occurs due to differential thermal expansion. The differing expansion coefficients cause interfacial stresses through elastic deformation effects exceeding adhesive strength; therefore, fracturing and material delamination results, rather than uniform stress which the system cannot sustain. The mechanism name is differential thermal expansion.
