对海冰的非线性物理力学性质进行了总结，特别关注了海冰破坏的韧脆转变机制以及微裂纹演变对海冰性质的影响。 - After pretorsion the successor tensile yield limit and strength limit both improved very highly , but the trend of the increase of the strength limit was suspended till the pretorsional capacity reached 17 , when the pretorsional capacity was greater than17 ( prestrain value was 81 . 19 % of total strain ) , the successor strength limit rapid failed and approached the yield limit . this illustrate the a3 steel specimen translate from plasticity into friability after pretorsion strengthen . when the specimen was operated by tension - torsion action , the yield limit had very large improved , but the strength limit changed very little . furthermore , the trend of the increase of the strength limit was suspended till the pretension capacity reached 0 . 25 ( prestrain value was 66 . 93 % of total strain )
A3钢试件在预扭转后，后继拉伸屈服极限和强度极限均有很大提高，但强度极限的增大趋势到预扭转量为17为止，预扭转量大于17 (预应变值为总应变的81 . 19 )后强度极限迅速下降，与其屈服极限接近，这说明a3钢试件经预扭转强化后逐渐由塑性转化为脆性。该预应变值为a3钢试件的韧脆转变点。 a3钢试件在拉伸-扭转作用下，屈服极限有很大提高，但强度极限没有多大改变，而且，屈服极限的增大趋势到预拉伸量为0 . 25应变(预应变量为总应变量的66 . 93 )后就不再增加。
