Length tension unloading data

Three giant bands with a rest length of 18.5cm were tested by stretching from a rest length of approx 18.5cm to a length of approx 69.5 cm

T3 = readtable('GiantbandLTdata3.xlsx');
l0=18.5; % unstretched length of giantband. Appears to have a tollerance of 5mm
offset=l0-44; % zero extension for the tests was at 44
len3=T3.length+offset; % avoid using length as a variable as it is also a matlab function

Band1=[T3.B1 T3.B2 T3.B3];
Band2=[T3.C1 T3.C2 T3.C3];
Band3=[T3.D1 T3.D2 T3.D3];
plot(len3,Band1,'b',len3,Band2,'r',len3,Band3)
