	This traction does not fail or release energy; as COD increases, the traction keeps increasing. If you want to model failure, use a [[Triangular Traction Law\|trangular traction law]] instead. For example, to model a linear law that suddenly drops to zero stress at some critical COD, use a [[Triangular Traction Law\|trangular traction law]] with the same elastic slope, enter the critical COD (&delta<sub>c</sub>), and set its [[Triangular Traction Law#Traction Law Properties\|delpkI and/or delpkII parameters]] to 1.
