murtumuspisteessä

murtumuspiste refers to the critical point at which a material subjected to stress ceases to deform elastically and begins to undergo permanent deformation, eventually leading to fracture. This concept is central to the fields of material science and structural engineering, as it determines the limits of safe load-bearing for components. In Russian and other inflected languages, the word’s case forms are used to indicate location or state, such as murtumuspisteessä, meaning “in the breaking point.”

The determination of murtumuspiste is typically performed through a tensile test in which a sample is pulled until it breaks. The stress–strain curve produced during the test shows a distinct maximum; the stress value at this maximum is the ultimate tensile strength, sometimes referred to as the breaking stress. The strain corresponding to the maximum stress is the elongation at break. The comparison of these values across different materials informs the selection of alloys or composites for specific applications.

In practice, knowledge of the murtumispiste is applied when designing load‑bearing structures such as bridges, aircraft components, and machinery casings. Engineers use factor‑of‑safety calculations that incorporate the breaking stress to ensure that the operating loads remain well below the material’s critical limit. Standards for construction and manufacturing often prescribe minimum breaking stress values for products, and testing is required to verify compliance. The murtumuspisteissi literally captures the moment in which a component transitions from elastic to plastic behavior and is a fundamental parameter in failure analysis, quality control, and the overall assessment of mechanical reliability.
