FAQ

What is the Normal Stress?

Normal Stress is stress that occurs when a member is loaded by an axial force. Normal Stress is usually measured using the Newton per Square Millimeter for Pressure. Note that the value of Normal Stress is always positive.

Can the Normal Stress be negative?

No, the Normal Stress, measured in Pressure cannot be negative.

What unit is used to measure Normal Stress?

Normal Stress is usually measured using the Newton per Square Millimeter[N/mm²] for Pressure. Pascal[N/mm²], Kilopascal[N/mm²], Bar[N/mm²] are the few other units in which Normal Stress can be measured.
