The 02% strain offset approach is mostly used to calculate the yield stress and serves as an efficient method for crosslab comparisons of measured material properties However, it is difficult to accurately determine the yield of the bone Especially when computational models require accurate material parameters, clarification of the yield point is neededFor me, yield stress (either 02% proof stress or upper yield stress depending on whether or not there is a yield point) is a special point in the stressstrain curve measured using a tensileFILM TYPE DENSITY (g/cc) YIELD of 1 MIL UNIT WEIGHT OF 1 MIL FILM;

0.2 yield strength calculation

0.2 yield strength calculation-The stress which gives rupture is called the ultimate strength or the tensile strength;The 02% (0002) is a value of strain, which is arbitrary, but it covers somewhat the uncertainty of when a given material actually departs from the purely linear (elastic) relationship between stress and strain Let l = length, then strain ε = (l l o)/l o, where l o = original length (usually the gauge length)
