Linear elastic fracture mechanics (LEFM) has limitations for analyzing the fracture behavior of rigid polyvinyl chloride pipe materials. Fracture behavior shifts from notch‐insensitive, yield‐stress‐controlled to brittle, LEFM‐controlled as temperature decreases and displacement rate increases. Even under the most brittle conditions, the fracture toughness is sufficient to resist most anticipated flaws such as scratches.
