The failure of steel refers to its inability to withstand applied loads or stress, leading to structural collapse or deformation. This can occur due to various factors, including excessive loading, fatigue, corrosion, and poor manufacturing processes. Common modes of failure include brittle fracture, ductile failure, and fatigue crack propagation. Understanding these failure mechanisms is crucial for the design and maintenance of steel structures to ensure safety and reliability.

What happened to the ultimate tensile and yield strength of most of the metals when temp falls?
building will collapse due to steel failure
What is a under-reinforced section in design of beam?
An under-reinforced section in beam design refers to a concrete beam that has insufficient tensile reinforcement to prevent failure by yielding of the steel before crushing of the concrete. This condition is typically characterized by a lower ratio of steel reinforcement to the amount of concrete, resulting in a ductile failure mode. In such a scenario, the steel reinforcement reaches its yield strength before the concrete reaches its ultimate compressive strength, allowing for some warning before failure occurs. This design approach is often preferred as it provides a more predictable and safer collapse mechanism.
What is the effect temperature on the impact of mild steel?
The impact behavior of mild steel is significantly influenced by temperature. At lower temperatures, mild steel becomes more brittle, increasing the likelihood of fracture upon impact. Conversely, at higher temperatures, the steel exhibits improved ductility and toughness, allowing it to absorb more energy before failure. This temperature dependence is crucial in applications where materials are exposed to varying environmental conditions.
What is strain to failure?
strain-to-failure
The fatigue strength of mild steel is?
The fatigue strength of mild steel refers to the certain conditions whereby the mild steel suffers fatigue failure.
What are Three factors of a steel structure failure?
Three factors that can contribute to steel structure failure include inadequate design, which may not account for load requirements or environmental conditions; material defects, such as flaws in the steel that compromise its strength; and improper construction practices, including poor welding or incorrect assembly that can lead to structural weaknesses. Additionally, corrosion over time can weaken steel components, further increasing the risk of failure.

What is the Difference between the Upper and lower yield stress in mild steel?
Lower YS is that point at which the steel flows elastically and failure takes place at upper YS.
What is stronger stainless steel or cold steel?
Depends on type and temperature range. Generally cold drawn steel is stonger in the drawing direction, but if it's a very cold or very hot application then stainless steel is a good choice. Technically I think CS that is very cold would make it stronger, but very brittle so any minor pertubations will cause failure, and failure will occur with no deformation warning.

Is it o.k. to use carbon steel pipe with brass valves?
There are instances when corrosion occurs at the junction of a carbon steel pipe and a brass valve. This is often the result of a pipe threading failure.
What happened to the ultimate tensile and yield strength of most of the metals when temp falls?
building will collapse due to steel failure
What is an under reinforced beam?
Under reinforced is that in which provided steel ratio is less than balanced steel ratio. Concrete beams are designed as under reinforced beams. The reason is that the failure start by yielding of steel instead of crushing of concrete. Mian Yaqoob
Is mild steel ductile at room teperature?
Yes, it is - it has a yield point and can strain quite a bit 20% or so before failure
Can a 4 inch steel pipe handle a 50000 pound axial load?
Steel has a crush strength of 95,000 psi and a tensile strength of 55,000 psi. A Sch. 80 - 4" steel pipe has a cross-sectional area (of steel) of 4.407 sq. in. This can handle a load in tension of ~242,000 pounds before failure. And a load in compression of ~ 418,000 pounds before failure. 50,000 pounds is well within the factor of safety for both loads in tension or in compression, provided there are no shear forces applied.
