-So, how are stress and strain connected?  For isotropic materials, such as most metals, there are two values that relate values of stress and strain and fully describe a material's behavior when forces are applied.  These are the **elastic modulus** and **Poisson's ratio.**+How are stress and strain connected?  For isotropic materials, such as most metals, there are two values that relate values of stress and strain and fully describe a material's behavior when forces are applied.  These are the **elastic modulus** and **Poisson's ratio.**
  
 The elastic modulus is a measure of the stiffness of a material.  For a given value of stress pulling on an object, increasing the elastic modulus (increasing the stiffness) causes less strain (less deformation of the object).  The following Scan&Solve model shows the effect of changing the elastic modulus. The elastic modulus is a measure of the stiffness of a material.  For a given value of stress pulling on an object, increasing the elastic modulus (increasing the stiffness) causes less strain (less deformation of the object).  The following Scan&Solve model shows the effect of changing the elastic modulus.

 As long as the material is not yielding, the elastic modulus and Poisson ratio are all that is needed to analyze material behavior under load.  For Scan&Solve's default materials, the elastic modulus and Poisson ratio can be seen in the custom material interface. These two material parameters play an important role in material selection for designs, particularly when the deflections are to be minimized. As long as the material is not yielding, the elastic modulus and Poisson ratio are all that is needed to analyze material behavior under load.  For Scan&Solve's default materials, the elastic modulus and Poisson ratio can be seen in the custom material interface.
