This steel has high toughness and is resistant to impact.
We conducted a test to evaluate the fracture toughness of the material.
強度 refers to strength (resistance to deformation or failure under load), whereas 靭性 specifically refers to toughness (energy absorption before fracture).
Standard kanji spelling for material toughness. The variant 靱性 is also used.
Variant kanji form; 靭性 is more common.
Mixed kana-kanji spelling, occasionally seen in technical contexts.
Compound of 靭 (じん, 'tough, pliable') and 性 (せい, 'property, nature'). The kanji 靭 is a variant of 靱; both are used in technical terms for toughness.
