Can we use kink on Y axis?

Answer: yes we can use kink on y and x axis at the same time.

How is a stress-strain curve plotted?

Stress-strain curve for this material is plotted by elongating the sample and recording the stress variation with strain until the sample fractures. By convention, the strain is set to the horizontal axis and stress is set to vertical axis.

Where in the stress-strain curve is valid?

True stress-strain curves obtained from tensile bars are valid only through uniform elongation due to the effects of necking and the associated strain state on the calculations.

Can we use kink on Y axis in bar graph?

Yes a kink can be made on the Y axis of a graph also just as we make it on the X-axis. Consider the case when the values of Y for different values of X are, say, 100, 103, 101 and 98. If we plot the values and make a graph without a kink, we would not see much of a difference between these four points.

Can we draw a kink in bar graph?

we can use kink in bar graph. If the previous class is easy to plot as 0-100 and then the mid point 50 can be used, so really no need to draw the kink. Supposing your class intervals start from 40-50, then next one 50-60, 60-70 etc. For the frequency polygon all you need is the mid point of the previous class.

What is strain in stress-strain curve?

A stress-strain curve is a graphical way to show the reaction of a material when a load is applied. Stress is the ratio of the load or force to the cross-sectional area of the material to which the load is applied. Strain is the ratio of the material deformation to the initial length.

What is the difference between engineering and true stress-strain curve?

The curve based on the original cross-section and gauge length is called the engineering stress-strain curve, while the curve based on the instantaneous cross-section area and length is called the true stress-strain curve. This shows the cross-section of the specimen has changed during the experiment process.

What is yielding in stress-strain curve?

In materials science and engineering, the yield point is the point on a stress-strain curve that indicates the limit of elastic behavior and the beginning of plastic behavior. Below the yield point, a material will deform elastically and will return to its original shape when the applied stress is removed.

What is proportional limit in stress-strain curve?

So, the proportional limit is defined as the highest stress at which the stress-strain curve is a straight line. Below the proportional limit, there is no permanent deformation in a structure, that is, the object returns to its original position after the removal of applied force.

Can we use kink in bar graph?

we can use kink in bar graph. If the previous class is easy to plot as 0-100 and then the mid point 50 can be used, so really no need to draw the kink. Supposing your class intervals start from 40-50, then next one 50-60, 60-70 etc.

Where does the kink go on a graph?

A kink is a zig-zag line that is usually drawn in the x-axis near the origin when the scale on the axis does not start from zero. A kink denotes the missing divisions.
