Mild steel 1 Young;s modulus 1219.5 Yield strain and stress (0.4101,500.08) Failure stress and strain :not able to find because the given data shows the experiment did not reach the failure point. if the material stress and strain does not reach a failure point ,what dose it means , does it means that the material is more stronger?
3. A structural component is made from a steel alloy with a plain strain fracture toughness of 77.0 MPa √m and a yield strength of 1400 MPa. The dimensions of the component allow it to be modeled as a wide plate. (a) If the design stress is half of the yield strength and Y =1, determine the critical flaw size, a. (b) If the flaw size resolution limit of the flaw detection equipment is 4mm, determine if a critical flaw can be detected. Consider both an internal flaw and a surface flaw.

A manufacturing process that unintentionally introduces cracks to the surface of a part was used to produce load-bearing components. The design requires that the component be able to withstand a stress of 450 MPa. The component failed catastrophically in service. You are a failure analysis engineer who must determine whether the component failed due to an overload in the service or flaws from the manufacturing process. The manufacturer claims that the components were polished to remove the cracks and inspected to ensure that no surface cracks were larger than 0.5 mm. the manufacturer believe the component failed due to operator error. It has been independently verified that he 5 cm diameter part was subjected to a tensile load of 1 MN (106 N) The material from which the component is made had a fracture toughness of 75 MPaÖm and ultimate tensile strength of 600 MPa. Assume external cracks for which f = 1.12. Who is at fault for the component failure, the manufacturer or the operator?…

After the yield region in the stress-strain curve the strength up to ultimate value because: -Molecules orientation in the direction of applied stress -Molecules fails to withstand the applied stress -Molecules orthogonal to the axis of applied force The following figure shows typical engineering tensile stress vs. strain curves, where: * Stress Strain - Points A, C, E and F correspond to the tensile strength and elongation at yield - Points A, B, D and F correspond to the tensile strength and elongation at break Points A, C, E and F correspond to the tensile strength and elongation at break
The theoretical failure strength is significantly higher than the empirical failure strength of polycrystalline materials, even when they are highly polished because: a) Polycrystalline materials have little or no capacity for plastic deformation, so they have lower failure stresses b) Plastic deformation in polycrystalline materials adsorbs energy which reduces their failure strength c)The energy needed to break the atomic bonds in crystal lattices is lower in polycrystalline materials as compared to in single crystals d)Polycrystalline materials contain internal discontinuities

10- A structural component in the form of a wide plate is to be fabricated from a steel alloy that has a plane-strain fracture toughness of (100 MPa mº-5) and a yield strength of 850 MPa. The flaw size resolution limit of the flaw detection apparatus is 3.0 mm. If the design stress is one-half the yield strength and the value of Y is 1.0, determine critical flaw length and whether it is subject to detection.
