There are several forms of strength failure
Thread Content
I recently saw a question asking how many forms of strength failure there are Some replied: ductile fracture, brittle fracture, fatigue fracture, corrosion fracture, creep fracture. Another answer is: blasting, excessive deformation. I’m a bit unclear about the concept of strength failure. I’d like to ask fellow sailors, how should I respond?
The failure modes of pressure vessels include: (1) strength failure: ductile fracture, brittle fracture, fatigue fracture, creep fracture, corrosion fracture； (2) Stiffness failure ； (3) Instability failure ； (4) Leakage failure.
Failure modes of pressure vessels: strength failure, stiffness failure, and stability failure – a total of three major failure types. How did another type of failure, namely leakage failure, appear? How can leakage failure be listed alongside these three main types of failures?
There is no so-called standard answer to this kind of question. It is recommended that the poster study *GB/T30579-2014, Identification of Damage Modes in Pressure Vessels*.
Excessive deformation should not be considered a strength failure; it should rather be regarded as a stiffness failure or instability.
The book \"Process Equipment Design\" mentions leakage failure.
