Young’s modulus of rubber是多少啊.

Young’s modulus of rubber是多少啊.
首先橡胶是粘弹性或超弹性材料,直接说他的杨氏模量是不准确的,不过用新虎克定律来表示它的应力应变关系时,可以近似得到一个杨氏模量
在微小应变的假设下,一般橡胶的杨氏模量可以取0.01-0.1GPa
以前做过轮胎的研究,不同的胶料配比的杨氏模量是不一样的,具体可以通过做材料力学试验测定.
希望有所帮助.

杨氏模量??

young's modulus of bones Young’s modulus of rubber是多少啊. Young’s Modulus of steel and nylon分别是多少? What's the Young's Modulus of the nylon wire and the steel wire? Young's modulus (E) is measure of the stiffness of an isotropic elastic material. isotropic在物理中的意思Young's modulus (E) is measure of the stiffness of an isotropic elastic material 英语翻译Attributes like wear resistance,deformation behavior,tensile strength,aswell as modulus of elasticity or Young’smodulus are connected with the termhardness.这句中的young's modulus什么意思 flexural modulus 和 young's modulus 是一回事吗?看到一种树脂杨氏摸量是7GPa,flexual modulus 是13-14 GPa,差这么远的. 杨氏模量和弹性模量的区别我无聊.我是看到百度知道里关于这两个模量的回答是错误的,所以重新写一条.杨氏模量(Young's modulus),又称拉伸模量(tensile modulus),只是弹性模量(elastic modulus o 英语翻译AM-Frequency Sweep TestThe Bohlin’s Dynamic Shear Rheometer (DSR) was used to determine the complexshear modulus (G*) of AM at high and intermediate temperatures.The frequencysweep test was conducted at frequency levels of 1 Hz through most of the young people enjoy__ jay chou's songs, what’s the ()of your grandma?she looks very young! 翻译句子what's the opposite of the young 英语翻译这个是一片文章上截下的,希望有人能帮我翻译一下,It is worth noting that the FCNs-fillednanocomposites show an increase in Young’s modulus andtensile strength from 0.5 to 344 MPa and 4.3 to 14.9 MPa,respectively, with Which one of the following materials has the highest modulus of elasticity?a.aluminumb.diamondc.steeld.titaniume.tungsten Holidays of S.R.Vietnam 怎么翻译 英语翻译英翻中it's a topic of CCTV9 DIALOGUE---china,a dream desinaiton of young EXPATS shear modulus是什么意思
