What happens when the material is stressed beyond the yield point?

Q: What happens when the principal stresses act on the element?

A: In this problem, a shaft with moment and torque applied at the free end and one is fixed. And, here…

Q: What is Circumferential Stress?

A: Circumferential Stress When pressure inside thin pressure vessel exceeds it exerts force from inside…

Q: What is the Allowable Stress Design?

A: In Allowable stress design, the maximum stress (σmax) that a member will endure under a given…

Q: How is the torsion test performed to determine the material’s ultimate shear stress?

A: A torsion test is a destructive type of testing used to find the properties of specimen under stress…

Q: What is the permanent strain?

A: Strain: When a force is applied to any system, they deform based on the applied force. The…

Q: Why is it not necessary to use stress concentration factors if the material is ductile?

A: Stress concentration is a location in a member under load where the magnitude of stress is…

Q: What is the Conventional Stress-strain show with a diagram?

A: A ductile material subjected to a tensile test passes through different stages before reaching the…

Q: What does the modulus of the toughness of material represent?

A: The modulus of toughness is the measure of how much strain energy can a material absorb before the…

Q: What are the important points on the stress-strain diagram?

A: The stress-strain diagram for a material explains the relationship between the stress and strain of…

Q: When does the magnitude of stress increase?

A: When a body undergoes deformation under normal or shear forces/loads, then it undergoes…

Q: What are the principal strains?

A: Principal Strain: Maximum and minimum normal strain possible for a specific point on a structural…

Q: Where is maximal torsional stress experienced?

A: The maximum shear stress is experienced at a section where the applied torque is maximum. This…

Q: If the material is ductile, how is the failure usually specified?

A: Ductile failure is one in which material undergoes plastic deformation before separation, It…

Q: What is the neutral plane of a material that is being bent?

A: When the force applied on the beam perpendicular to the centroidal axis results bending in the beam.…

Q: An example of two types of stress?

A:

Thermal Properties of Materials

In mechanical engineering, the thermal property is represented as the physical quantity that is relevant to the application of heat. The thermal properties are evaluated by variations in any specific material due to low heat or high heat. The quantities that influence the thermal property of the materials are mass, density, temperature, and many others.
