What is strain energy theory?
The strain theory is a state of deviation from bond angle of a normal tetrahedral angle.
What is the relationship between stress and strain?
Stress is the load per unit area acting within a material. It can be thought of as the internal resistive response of a material to an externally applied pressure.Strain is the change in shape of an object in response to external pressure or internal stress. To complicate matters, strain causes the transmission of stress through an object (as in simple terms the strain causes an internal "movement" causing one part of the inside of an object to press against the material next to it generating stress in this region, this in turn can cause more strain and so on!).There are a number of differing types of strain, for example axial strain is defined as the change in length relative to the original length of an object (e.g. a steel wire being stretched). This change in shape is also called deformation. Volumetric strain occurs when an object is squashed or pulled on all sides leading to a change in volume.
What is strain hardening?
When ductile material is loaded, when stress reaches yield and if the load continues, as long as load is not high enough to break material, the material is strain hardened when returning to no load. That means its yield strength will be higher than before, and the material is stronger.
What is the deformation between strain and deformation?
First of all i guess the right question is difference between strain and deformation. Actually the strain is deformation in a material over its original length. So strain is a relative quantity while deformation is simply change in length, hence absolute and is new length minus original length. Strain= deformation(L2-L1)/original length(L1)
What is relastion between strees and strain?
In material science, strain does not depend on stress; rather it's the reverse. Stress is proportional to strain, as stated by Hooke's Law, until the material reaches its elastic limit.
What is the difference between normal strain and shear strain?
The normal strain is a deformation caused by normal forces such as Tension or Compression that act perpendicular to the cross-sectional area, while the shear strain is a deformation obtained from forces acting parallel or tangential to the cross-sectional area.
What is it meant by shear force?
Force acting on a substance in a direction perpendicular to the extension of the substance, as for example the pressure of air along the front of an airplane wing. Shear forces often result in shear strain. Resistance to such forces in a fluid is linked to its viscosity. Also called shearing force .
What are the causes of deformation?
Deformation of materials (called strain) is a response to forces acting on those materials (called stress).
What is torsional force?
"Torsional strain" is the strain induced by applying torque. Basically, it is the strain imposed on a body by twisting it. (Such as the strain that a bolt endures when you use a wrench on it.)
What is the correct definition of strain?
"strain" refers to the deformation or change in shape of a material when subjected to an external force or load. It is typically expressed as a ratio, either in terms of the change in length (linear strain) or the change in angle (angular strain) relative to the material's original dimensions. Strain is often represented using the symbol "ε" (epsilon) and can be described as: ε = ΔL / L Where: ε is the strain. ΔL is the change in length. L is the original length of the material. Strain is a measure of how much a material deforms under stress, and it can be used to study the material's mechanical properties, such as its elasticity and ability to withstand external forces without permanent deformation or failure. It is an important concept in fields like materials science, civil engineering, and mechanical engineering.
What Strain which causes material to twist?
tension
What is strain energy theory?
The strain theory is a state of deviation from bond angle of a normal tetrahedral angle.
Where does the stress-strain curve end?
when the material fails
What is the elastic forces that stretches or pulls matter?
Elasticity is a type of strain that is recoverable, it is not a force. However it is caused by an imposed force which generates a stress below the yield strength of a material. If the force is pulling or stretching a material it is known as a tensile force or stress.
What information might you get from stress-strain curve?
As a simple answer, from this curve the mechanical properties of the material can be found such as: Elasticity Modulus (E) which is the proportion of Stress to the Strain, the higher value means under a fixed value pressure the material oppose more to deflect. Reversely, the lower value shows that the material is more flexible. Other information such as Yield Strength, Ultimate Tensile Strength and also from the area below this curve the material toughness can be obtained.
