← HistoryWhich risk increases when thermal stress exceeds Mughal pietra dura threshold?
A)Material experiences catastrophic crack propagation✓
B)Inlay dislodges due to uniform expansion
C)Supporting structure undergoes plastic deformation
D)Water system leaks exceed supply
💡 Explanation
Cracking initiates most rapidly because linear thermal expansion mismatches at grain boundaries cause increased internal stress beyond the material tensile strength, therefore fractures propagate readily rather than a uniform expansion failure given thermal dynamics limitations.
