Hello, so here is my problem. 1. The problem statement, all variables and given/known data I am given tensile data, which is displacement (mm) and load (kgf). also im given width(mm), thickness(mm), guage length (mm) and cross-head speed (mm/min). How do i make a stress strain curve from this? 3. The attempt at a solution So far i have multiplied width by thickness to find cross sectional area (in metres squared). Then i divide load (kgf) *9.8/cross sectional area (m^2) to find stress. and displacement (metres) over guage length (metres) to find strain. im getting around 65,000,000 pascals for maximum stress at around 40% strain. its for PVC. does that make sense? thanks!
