suurus, mis näitab materjali elastsust ja avaldub pinge σ ja elastse deformatsiooni ε suhtena kujul: E = σ / ε, quantity equal to normal stress σ divided by linear strain ε, under given conditions, thus E = σ / ε, unit of measurement of an object's or substance's resistance to being deformed elastically (i.e., non-permanently) when a stress is applied to it
