# stress strain curve properties analyse

There are two components given with each stress-strain curve. Determine the component that maximise the load carrying capacity and that maximise the elastic deformation per unit applied load.

Is it right for the maximum load carrying capacity to look for the highest yield stress and for the maximum elastic deformation per unit applied load to look for the highest strain at failure?

• Short answer ... yes and no. Longer answer .. Draw a free-body diagram for the system and relate what is being asked to what is measured in the test. Making this modification to the question will help you appreciate how a complete answer can then be obtained. Oct 18 '18 at 16:04
• Is there an image of the strain-stress curves? Oct 18 '18 at 16:32
• It is measured the load and the extension. I don't know what load carrying capacity and elastic deformation per unit applied load mean. What are the relationships between them and load and extension?

Do you know how a typical stress-strain curve looks like? Take a look at this image:
