Fracture stress is only less than ultimate tensile strength in an engineering stress-strain diagram. This is because the material will experience a maximum stress before it undergoes necking. After necking, stress will decrease again until the material snaps.
Ultimate stress is defined as force to fail divided by area of the section. Since in actual failure the section area is necked down and thus smaller, true stress to failure is actually a bit higher
Elastic Potential
after ultimate tensile strength (UTS)
It is the ultimate strength of a material subjected to tensile loading. In other words, it is the maximum stress developed in a material in a tension test.
The greatest stress that a material can resist before breaking is called the ultimate tensile strength. It is the maximum amount of stress a material can withstand without breaking under tension. Different materials have different ultimate tensile strengths, and it is an important property to consider for designing and engineering structures.
No the moment of resistance is a defining parameter that can be used to calculate the stress in a cross section of a given material that is subject to flexural loading. The ultimate flexural strength is a numerical value of stress at which the material will crack, tear, rip etc. Think about ultimate tensile strength and the value of Young's Modulus. Young's Modulus is not defined at the point of 'necking' and therefore the ultimate tensile strength cannot be computed from Young's Modulus and Hook's Law, but the UTS is an empirically defined value.
Allowable stress would normally refer to design using Allowable Strength Design, also known as working strength design. In this the allowable stress is usually a fraction of the yield strength and can be different for uniform tension and bending. Typically mild steel has a yield strength of about fy=250MPa with allowable stresses in Tension, 0.6fy=150MPa Bending, 0.66fy=165MPa

Ductility is an objects ability to deform under tensile stress.

Tensile strength is the ultimate capacity of the material to resist a tensile load regardless of deflection.Tensile modulus also known as Young's modulus, is a measure of the stiffness of an isotropic elastic material. It is defined as the ratio of the uniaxial stress over the uniaxial strain. It is determined from the slope of a stress-strain curve traced during tensile tests conducted on a sample of the material.
Stainless Steel 316 properties - Tensile Yield Strength (.2% offset): 276 MPa / 40 kpsi Ultimate Tensile Strength: 621 MPa / 90 kpsi Not sure which you're looking for, so both in case. Yield strength uses the slope of the initial elastic region of the stress-strain graph to determine a 0.2% offset along the curve; ultimate tensile strength is essentially the maximum stress experienced along the stress-strain curve.
tensile stress is the force ehich applies on a body and the force exert by this body against this force is called tensile strength... simply tansile strength measure the force required the force to pull yhe body like rope and wire .
Mild steel is a fairly general classification and can cover a considerable variation in material properties. Cold drawn grades in particular will have a higher tensile strength than hot rolled. Something like 400 MPa for yield stress and 500 MPa for ultimate tensile strength is quite common.
