Schematic image comparing a skin fissure to an erosion and an ulcer. The surface of the knuckles of a hand with xeroderma, showing skin cracking (generalized skin fissuring). A skin fissure is a cutaneous condition in which there is a linear-like cleavage of skin, sometimes defined as extending into the dermis. [1] It is smaller than a skin ...
If the material breaks on a flat plane, the fracture was brittle, and if the material breaks with jagged edges or shear lips, then the fracture was ductile. Usually, a material does not break in just one way or the other and thus comparing the jagged to flat surface areas of the fracture will give an estimate of the percentage of ductile and ...
Fracture is the appearance of a crack or complete separation of an object or material into two or more pieces under the action of stress.The fracture of a solid usually occurs due to the development of certain displacement discontinuity surfaces within the solid.
Stress corrosion cracking (SCC) is the growth of crack formation in a corrosive environment. It can lead to unexpected and sudden failure of normally ductile metal alloys subjected to a tensile stress, especially at elevated temperature.
Ahead, you’ll find pictures of common skin rashes, plus symptoms to look out for. It’s important to note that rashes can look different depending on your skin tone. Some conditions might not ...
A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. [1] [2] Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease.

Generally, a splinter causes an initial feeling of pain as the sharp object makes its initial penetration through the body. Through this penetration, the object cuts through the cutaneous layer of the skin, and settles in the subcutaneous layer of the skin, and can even penetrate further down, breaking the sub-cutaneous layer, settling in muscle tissue, or even the bone.
