运用损伤力学理论,从应变等效性假设出发,基于复合材料结构"点应力"准则的概念,提出了一种考虑残余应变影响的刚度下降疲劳损伤模型。
4) sinkage stiffness

下沉刚度
1.

补充资料:单纯性下肢浅静脉曲张
单纯性下肢浅静脉曲张
simple varicose of superficial veine of lower limb
常与职业因素有关,经常从事站立工作的人,血柱的重力,尤其是负重者的腹腔内压力经常升高,可以破坏原来正常或有先天性缺陷的髂外静脉和股静脉的瓣膜,或者直接酿成大隐静脉瓣的撑扯性破坏,静脉因而有扩张、弯曲及伸长,其后可形成不均匀的结节状曲张。由于血液停滞使静脉周围组织因缺氧而发生营养不良,毛细血管壁的渗透性增加,液体渗入组织内,产生水肿。该渗液含有多量蛋白质,如此使成纤维细胞增生更著。淋巴系统亦受到损害,水肿日益严重。淤血结果,红细胞亦渗出而产生色素沉着,多位于小腿远端近内踝处,其后多在小腿下1/2段发生广泛的色素沉着。该病多发生于大隐静脉,后期才累及小隐静脉。患者可全无自觉症状,或于久站时感小腿胀满感,后期可有色素沉着及溃疡的形成。
