information library materials

[Joshua662]

Save guys don't know if this is the right section to post my question but I try, I'm doing my personal library of the materials I usually use in production, but I've resurrected of the difficulties, the never before difficulty was 6000 find the technical characteristics of the materials but solved with matweb, second problem not all the data are present in this table I miss coefficente of thermal expansion and limit proportionality, as I can do to make these

Hello, guys, I solved this problem, but now, can you help understand something? I have taken as reference for lp "limit proportionality" the yielding load by dividing it for two so I am half the limit of proportionality. . right as what? then for the thermal expansion better take the coifficent reported on the site matweb cte linear as reference temperature from 0 to 100 °c or in the middle of the scale that is between the 100 °c and 700°c? then in the end how can I transform thermal expansion from μm/m-°c to k_deg as a catia port?

hi to all, I wanted to ask you how to calculate the limit of proportionality in the technical sheet of a new material having the classic table information: rm, rp, hb hardness hello thanks
