In any failure analysis it is important to get as much information as possible from failed part it self along with an investigation of the condition at the time of failure.
same question to be asked are:.
1. How long the part was in service?
2. What was the nature of the stress at the time of failure? ......

A stress that causes a material to fracture where the fracture opens or spreads apart is?
tension
What is the purpose of samples of impact test being notched?
In a charpy impact test, the purpose of the notch is to provide a point of fracture at the same point for each material, to make it a fair test.
What is the fracture of sulfur?
sulfurs fracture point is 3.62 g/cu
What sort of properties do materials which show brittle fracture have?
Their breaking strength is smaller than their shear strength. Once the strain on the material surpasses the elastic limit, the material will fracture and in process known as brittle fracture. This plastic deformation is permanent and irreversible.
WHAT is sulfur's cleavage or fracture?
Sulfur has no cleavage and it's fracture point is 3.62 g/cu.
Why do most fractures occur at the middle third of the femur instead of at the ends?
Simply put, it is easier to break any length of uniform material in the middle third than at the ends. The greater the distance from the end point of the material to the potential fracture point, the greater torque that is able to be applied. So it takes less force to apply the necessary torque to fracture the bone in the middle third than it does near the ends.
How do you calculate fracture toughness from impact energy through impact test?
Impact test gives toughness value which is energy absorbed by material per unit volume.. From test like charpy test value of energy absorbed by the specimen can be calculated directly by getting the height of pendulum after impact.... whereas fracture toughness is totally different subject which comes into picture after formation of crack in the material. Methods of calculation of fracture toughness depends upon the type of material (brittle or ductile). Resistance curve is used to find the fracture toughness.
What is the difference between fracture and rupture?
Fracture is the cracking or breaking of a hard object. Rupture is the sudden bursting of a soft material object.
Is it true Elastic deformation occurs when a material deforms as stress is applied?
Up to a point, it is possible to elastically deform any material. If the force is released, the material relaxes back to its original shape. If a material is deformed too much, the deformation becomes permanent (plastic deformation) or fracture will occur in a non-ductile material such as glass.
What material is more brittle wood cast iron steel or glass?
Cast iron is very brittle in its basic form, with yield point very close to fracture point. However, glass is the most brittle, having no yield point - it is perfectly elastic before failure
What is the fracture toughness of mild steel?
The fracture toughness, or the property that describes the ability of a material containing a crack to resist fracture, of mild steel is around 50 K (where 'K' is the stress intensity factor).
What is the different between failure and fracture?
failure-loss of load carrying capacity. fracture-breaking of material in two piece due to application of load.
