What is ,Stress,-Strain Curve? ,Stress, strain curve is the plot of ,stress, and strain of a material or metal on the graph. In this, the ,stress, is plotted on the y-axis and its corresponding strain on the x-axis. After plotting the ,stress, and its corresponding strain on the graph, we get a curve, and this curve is called ,stress, strain curve or ,stress, strain ,diagram,.
