noun
plastic limit
Technical term in soil mechanics and materials science: the water content at which a soil or material transitions from a plastic to a semisolid state.
塑性限界は、土の工学的性質を評価する重要な指標です。
The plastic limit is an important index for evaluating the engineering properties of soil.
Liquid limit: the water content at which soil behavior changes from plastic to liquid. Together with the plastic limit, it defines the plasticity index.
Plasticity index: the numerical difference between the liquid limit and the plastic limit, indicating the range of water content where the soil is plastic.
Compound of 塑性 (plasticity) and 限界 (limit). The term is a direct translation of the English 'plastic limit' used in geotechnical engineering.
