Which outcome is triggered when differential stress exceeds limit?

💡 Explanation

Brittle failure occurs when stress surpasses the rupture strength limit; therefore, fractures form, creating fault lines, because the material cannot deform plastically to relieve the stress rather than exhibit linear elasticity or viscous flow.
