Impact of Wood Moisture Content on Structural Integrity of Wood Under Dynamic Loads
The majority of mechanical wood properties are negatively affected by wood moisture within the hygroscopic range, disregarding the stress relaxation of wood at very low moisture contents (MC).

Nature of the Brittleness of Metals
The brittleness of material is considered as a specific manifestation of mechanical behaviour under load, which appears in the instability of the strength characteristic value under conditions of non-uniformity of the stress–strain state (SSS).

Problems of Multiscale Brittleness Estimation for Hydrocarbon Reservoir Exploration and Development
The study is focused on the problem of using geophysical data to estimate brittleness of rock masses for the needs of petroleum industry. Three main developed ways to estimate brittleness—mineral-based, log-based, and elastic-based brittleness indices ...
