Distortion energy theory is a failure criterion used in materials science to predict the onset of yielding or fracture.

• Also known as the von Mises yield criterion or the maximum distortion energy theory.

• It states that yielding occurs when the distortion energy per unit volume exceeds a critical value.

• It is based on the assumption that yielding is controlled by the accumulation of plastic strain energy.

• The theory is commonly used in the design of ductile materials and structur...read more

Warranty typically covers defects in materials or workmanship, while it does not cover normal wear and tear or damage from misuse.

• Covered under warranty: defects in materials or workmanship

• Not covered under warranty: normal wear and tear, damage from misuse

• Examples: a broken screen due to a manufacturing defect would be covered, but a cracked screen from dropping the device would not be covered
