Quasistatic loading, Mechanical Engineering

• For the ASTM dogbone specimens, the ¾ inch hole specimens, and the notched specimen tabulate the failure load, in pounds.

• Show plots of stress and strain for all specimens with strain gages according to the following:

For each ASTM dogbone specimen, make two plots:

 A plot showing axial stress on the y axis and axial strain on the x-axis.

A plot with transverse strain plotted on the y-axis, and the axial strain plotted on the x-axis. (This curve will be helpful for calculating the Poisson's ratio.)

For each stress concentration specimen plot axial stress versus strain (both gages) on a single set of axes.

For the 4-inch wide stress concentration specimen, plot the stress distribution across the line containing the strain gages for several values of applied load based on strain gage readings.

Observe the following for these plots:

To make a clean plot, remove any data following failure of the gages (due to shorting, debonding, or saturation). However, include valid nonlinear portions of all stress strain curves in the plots, if observed.

Remove extraneous data from the beginning of the test pertaining to the time between when DAQ was turned on and the actual beginning of loading.

Use error bars in at least one dogbone plot

For all dogbone specimen plots, the stress should be computed from the measured load divided by an appropriate cross-sectional area.

For the hole specimens use the define axial stress in the plots as the nominal stress (force divided by the minimum cross-section area across the hole). (This will allow direct determination of stress concentration factors.)
