Write a MatLab script file that solves the problem!!!
In a uniaxial tension test, a dog-bone-shaped specimen is pulled in a machine. During the test, the force applied to the specimen, F, and the length of a gage section, L, are measured. The true stress, 0,, and the true strain, &,, are defined by: FL 3 A LO &, = In where A, and L, are the initial cross-sectional area and gage length, respectively. The true stress-strain curve in the region beyond yielding is often modeled by: 0,= K The following are values of F and L measured in an experiment. Use the linearized form of the above equation determining the value of the coefficients K and m that best fit the data. The initial cross-sectional area and gage length are 4, = 1.25.10+m and Lo = 0.0125m. F (kN) 24.6 29.3 31.5 33.3 34.8 35.7 36.6 37.5 38.8 39.6 40.4 L (mm) 12.58 12.82 12.91 12.95 13.05 13.21 13.35 13.49 14.08 14.21 14.48
