Simple Strain and Deformation Flashcards
In strain and deformation relationship, If there is strain, there is blank
deformation
In strain and deformation relationship, If there is deformation, there is blank
strain
It is the change in size or shape
deformation
It happens when it experiences strain
deformation
It is the measurement of deformation
Strain
Who invented Hooke’s law
Robert Hooke
It describes how a material deforms under load
Hooke’s law
Change in length divided by the original length
Normal Axial strain
It undergoes angular deformation
Shear Strain
It causes layers of materials to slide past each other
Shear Strain
Strain is expressed in percentage or radians, and change per unit length because it is considered as blank
Dimensionless
It measure’s steel’s ability to deform elastically.
Youngs modulus
Constant Value of Youngs modulus in steel
200,000 - 210, 000 MPa
The higher the modulus, the blank material
Stiffer
It is a deformation that occurs along the axis of the force applied.
Normal Strain
It can either be elastic or plastic
Deformation
Give 3 practical Applications of Deformation
Building construction, bridge design, safety and standards.
Stress and strain are blank to each other
Directly proportional
If it exceeds to this point, the curve where this directly proportional relationship ends.
Proportional Limit
It is the highest stress that a material can withstand and returns to its original shape after removing load.
Elastic limit
It is where the material starts to have permanent deformation
Yield point
It is where the strain hardening phase happen
yield point
stress at failure
rupture stress
It is the design analysis phase
Nominal Fracture stress
It is relevant when analyzing failure modes.
True fracture stress
It is a test where a specimen is gripped between the jaws of testing machine
Tension test
Material’s element’s ability to resist deformation under axial load
Axial Rigidity
