Breaking strength
The breaking force is a term used in materials testing for the force that is required to break or tear a test specimen .
The breaking force is usually given as force (in N ) or as breaking stress (in N / mm²).
In tensile or bending tests , it is defined by the drop in force that occurs when the maximum force at which the material is still plastically deformed is exceeded . If the force falls e.g. B. by 20%, the universal testing machine recognizes that the sample has broken. The tensile strength of the material can be determined from the breaking force .
