Stress fracture
A break that occurs from repeated stress to a bone over time.
The medical terminology for this is a "stress fracture".stress fracturestress fracture
An acute fracture is a break in a bone that occurs quickly, rapidly and usually traumatically. A non-acute fracture is one that occurs over time, often because of repeated physical stress or impact placed on the bone.
Ductile deformation is when rock is given enough stress to break. If the stress is less, it will bend but not break.

Bending fatigue is the tendency of a material to break. This is usually applicable to metals after repeated stress is applied.

Ice wedging occurs when water seeps into cracks in rocks, freezes, expands, and creates stress on the rock. This repeated freezing and thawing cycle eventually causes the rock to break apart into smaller pieces. The broken fragments can further break down into soil particles through continued weathering processes.
The different types of stress that can affect rocks are compression, tension, and shear stress. Compression occurs when rocks are squeezed together, tension occurs when rocks are pulled apart, and shear stress occurs when rocks slide past each other in opposite directions. These stresses can cause rocks to deform and break, leading to the formation of faults and other geological features.
Tensile stress is the force that pulls rock apart, causing it to break or fracture. This type of stress occurs when rocks are stretched in opposite directions, leading to the formation of cracks or faults in the rock.
The process in which rocks first bend and then break is called deformation. Deformation occurs when rocks experience stress, which can be caused by tectonic forces, pressure, or temperature changes. Initially, rocks may bend or fold under this stress, but if the stress is too great, the rocks can eventually break or fracture.
