The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically The yield strength is often used to determine the maximum allowable load in a mechanical component, since it represents the upper limit to forces that can be applied without producingMinimum yield strength 38,000 psi Tensile strength 70,000 psi Allowable stress (70,000/35I'm trying to learn some new engineering, so if something I ask doesn't make sense remember I'm new to this I need to calculate how much force a part can take before breaking Material resin (Flexural Yield Strength 6752 psi) (Tensile Strength 3390 psi) (Density lbs/gal 964)
The point at which a material ceases to be elastic and becomes permanently plastic, the point at which it yields, is called its yield point The magnitude of stress at which this transition occurs is known as the material's yield stress or strength The yield strength is a material constant that represents the limit of its elastic behaviorFor example, aluminum has a yield strength of 14,000 pounds per square inch (or psi), copper has a yield strength of 10,000 psi, and steel, being an alloy of several different materials, has aWhen yield strength is reported, the amount of offset used in the determination should be stated For example, "Yield Strength (at 02% offset) = 51,0 psi" Young's Modulus of Common Engineering Materials
Ultimate tensile strength (UTS), often shortened to tensile strength (TS), ultimate strength,Apply tension to the steel plate with the cross heads using the software Continue applying tension until the plate fractures Record the load in pounds that was applied when the plate fractured As an example, the load was 5,000 lbs Divide the load at fracture by the area of the steel plate to determine the ultimate tensile strengthTo apply this rule, assume that yield strain is 02 percent, and multiply by Young's Modulus for your material σ = 0 0 0 2 × E \sigma = 0002\times E σ = 0002×E To distinguish this approximation from other calculations, engineers sometimes call this the "offset yield stress"

Yield Strength is the stress a material can withstand without permanent deformation or a point at which it will no longer return to its original dimensions (by 02% in length) Whereas, Tensile Strength is the maximum stress (usually represented in PSI) that a material can withstand while being stretched or pulled before failing or breakingTensile strength of steel will show us how much tensile stress the steel can withstand until it leads to failure in two ways ductile or brittle failure Ductile failure – think of this as the preliminary stage of failure, where it is pushed beyond the yield point to permanent deformationThe fracture strength is the point of strain (fracture point) where the material physically separates At this point, the strain reaches its maximum value and the material actually fractures, even though the corresponding stress may be less than the ultimate strength at this point
