KIc of mild steel is about 140 Mpa√m.
Based on the calculation of stress intensity in a cracked 6 inch schedule 40 pipe filled with 1000 psig water (about 6 Mpa√m), and without knowing anything further about the pipe’s environment, what failure modes are possible?
a. brittle fracture
b. ductile fracture
c. high cycle fatigue
d. low cycle fatigue
e. radiation embrittlement
f. thermal creep
This material may consist of step-by-step explanations on how to solve a problem or examples of proper writing, including the use of citations, references, bibliographies, and formatting. This material is made available for the sole purpose of studying and learning - misuse is strictly forbidden.The circumferential stress in the pipe from the 1000 psi internal pressure is calculated as: Pr/t. The value of t for 6" schedule 40 pipe is 0.28", therefore the circumferential stress is 10,714 psi....
