← HistoryWhich cracking risk increases significantly in 'pietra dura' inlay panels that overly constrained during thermal expansion?
A)Tensile stress exceeds material strength✓
B)Oxidation occurs along grain boundaries
C)Surface delamination increases the reflectivity
D)Capillary forces damage adjoining structures
💡 Explanation
Tensile stress concentrating along the boundaries because differential thermal expansion is constrained by the surrounding material, therefore cracking initiates rather than oxidation or delamination, which are surface phenomena less relevant to inlaid structures under compression.
