All About 52100 Steel (Properties,Strength,and Uses)
A material with a high fracture toughness generally fails in ductile fracture,while those materials with a low fracture toughness simply shatter.From its fracture toughness (15.4-18.7 MPa-m ½ ),52100 steel is clearly is prone to a more ductile fracture scenario,which is ideal for such steel.Crack Arrest and Static Fracture Toughness Tests of a Ship The recently standardized ASTM Test for Determining the Plane-Strain Crack Arrest Fracture Toughness K Ia of Ferritic Steels (E 1221) was modified for use with BIS 690 steel,an Australian low-alloy,700-MPa strength,quenched and tempered steel used for ship plate.Specimens of 50-mm thickness in longitudinal and transverse orientations were tested at -60°C with various depths of side

Fatigue and Fracture of Ship Structures - Fricke - - Major
Thicker plates are known to be more critical with respect to brittle fracture particularly as they support stress multiaxiality.The high fracture toughness in special areas successfully helped to avoid unstable fractures during the past years which had occurred in early times of welded ship structures.Fracture Mechanics MechaniCalcFracture toughness decreases as material thickness increases until the part is thick enough to be in a plane-strain condition.Above this plane-strain thickness,the fracture toughness is a constant value known as the plane-strain fracture toughness.
