tensile test 的speed of testing...请帮忙！！

windson

I would like to use Universal Testing Machine (Shimadzu, AG-100kNI) to
test tensile strength of a dog bone specimen (mild steel, thickness 6
mm, width 13mm, cross sectional of necking area of 13 width x 6mm thic
k),what was the recommendation speed of testing i should use?

有错请指教。。。

越慢的越准（有没有 option?) ，如果要compare diffenrent material, 最好set it as constant speed

嗨。。那你是test铁是吗？mild steel应该是不会被test speed影响的，印象中plastic才会。。。

strain rate在10^-2 和10^-4 之间可以拉出elastic到plastic region，具体速度还是问导师比较好。
