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.

When does Necking of a metal occur under tensile stress?
after ultimate tensile strength (UTS)
What is the tensile strength of plywood?
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.
What is the greatest stress that material can resist before breaking?
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.
Is ultimate flexural strength and moment of resistance the same in a reinforced section?
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.
What is the ultimate stress of mild steel?
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

Ultimate tensile strength?
the maximum stress which the material can bear without breaking is called the maximum tensile strength of the material

Different materials have different ultimate tensile strengths, and it is an important property to consider for designing and engineering structures.
What is breaking stress?
Breaking stress, also known as ultimate tensile strength, is the maximum stress that a material can withstand before it fails or breaks. It is an important mechanical property that helps indicate the strength and durability of a material under tensile loading conditions.
What are the three types of metal strengths?
The three types of metal strengths are yield strength, ultimate tensile strength, and toughness. Yield strength is the amount of stress a material can withstand before it starts to deform plastically. Ultimate tensile strength is the maximum amount of stress a material can handle before failure. Toughness indicates the ability of a material to absorb energy and plastically deform before fracture.
What is the ultimate tensile strength of mild steel. Show me the stress and strain diagram?
410 n/mm2
What is yield stress value for frp?
3000 MPa ultimate tensile strength (more than 10 times mild steel)
What is the maximum amount of stress a material can exert called?
The maximum amount of stress a material can exert is called the ultimate tensile strength. It is the maximum stress a material can withstand before breaking.
What is the difference between tensile strength and tensile stress?
Tensile strength is the maximum force a material can withstand without breaking, while tensile stress is the force applied per unit area of the material. Tensile strength is a property of the material, while tensile stress is a measurement of the force applied to the material.
The ability of a material to withstand permanent deformation under tensile stress without fracture is?
Ductility is an objects ability to deform under tensile stress.
