← ScienceWhich outcome occurs when exceeding silicon crystal's tensile strength?
A)Brittle fracture via crack propagation✓
B)Plastic deformation before failure
C)Increased piezoelectric charge generation
D)Transition to amorphous phase abruptly
💡 Explanation
Brittle fracture occurs under tension because cleavage plane weakness induces Griffith crack propagation, therefore a crack spreads rapidly, rather than deforming plastically due to limited dislocation movement in the tetrahedral crystal.
