Dynamic fracture toughness testing. Final report, 1 September 1985-28 February 1989

Technical Report ·
OSTI ID:5576105
;
An optical technique for measuring the crack-tip opening displacement of pre-cracked three-point-bend specimens subjected to impact loading was developed. Procedures for computing a dynamic Load-CTOD plot were also developed; this enables one to determine the dynamic fracture toughness. Finite-element analyses were used to verify and extend the procedures.
