碳钢的线胀系数? 我自己先来简单的回答一下,按道理说 alpha线胀系数只是个系数应该跟单位没有关系,caesar帮助里解释到alpha material coefficient of thermal expansion. there can be up to three thermal cases (corresponding to thermal cases t1, t2, and t3) defined for structural steel members. thermal effects on structural members are entered using thermal expansion coefficients in terms of in./in, mm./mm., i.e. unitless. the three thermal coefficients are entered after the density. 但是查国内相关标准只能查到碳钢的线胀系数是10.6*10-6/℃,如果不考虑单位直接输入0.000000106的话是不可以的,因为caesar只保留小数点后四位。 还望各位高手给予指点查看更多
