Aging of Elastic Bodies - full data set

All of our data sets are available here in a Matlab structure file under the name 'AllData_AoEB.mat'. The simulation code is attached as the Matlab script 'agingElasticModel.m'. Below are detailed instructions for using 'AllData_AoEB.mat' to recover the data from the paper: The data that is plotted in Fig. 1c, 1d, 2a, 4a and 4b contain 29 experimental runs and are available in the fields AllData.Fig1c, AllData.Fig1d, AllData.Fig2a, AllData.Fig4a, AllData.Fig4b. The force is recorded at 10Hz for all our experimental data. AllData.Fig1c: contains 29 fields named run#. Each field corresponds to one cyclic protocol with $t_w$ and $F_{max}$ as in AllData.t_ws(#) and AllData.Fmaxs(#). In each run, the accumulative displacement is specified as d_n, and the cycle time, $(n-1)t_w$, is specified as t_n. The field named 'inset' contains all the effective displacement aging rates $b_d$ and the initial displacement $d_{min}$ of all 29 experimental runs, which are presented in Fig. 1c. AllData.Fig1d: contains 29 fields named run#. Each field corresponds to one cyclic protocol with $t_w$ and $F_{max}$ as in AllData.t_ws(#) and AllData.Fmaxs(#). In each run, the normalized force difference on every iteration, $\Delta\tilde{F}$, is specified as Delta_F_tilde. The field named 'inset' contains all the power law values, $\gamma$, that are presented in the inset of Fig. 1d. AllData.Fig2a: contains 8 experimental runs (AllData.Fig2a.run#). Each run corresponds to a stretching period, as presented in Fig. 2a, and contains the force and displacement for the stretching part. The inset contains two vectors named 'Fmaxs' and 'DFs' that are plotted in the inset of Fig. 2a as the x and y axes, respectively. AllData.Fig4a: contains vectors named 't_ws' and 'Delta_F_tilde_1' that are plotted in Fig. 4a as the x and y axes, respectively. The field named 'inset' contains data of the F(d) curves at the initial stretching of all 29 experimental runs. AllData.Fig4b: contains vectors named 'b_ds' and 'b_ds_sim' that are plotted in Fig. 4b as the x and y axes, respectively. The matrix 'F_d_fit_params' contains the fitting parameters of all $F(d)$ curves (Fig. 4a, inset) in the vicinity of $F_{max}$. $F(d)$ is shifted such that $F(d=0)=0.01 N$. The fitting form is a second-order polynomial, $Ax^2+Bx+C$, where [A,B,C]=fit_params(n,:). AllData.RawData_figs_1_4: contains the raw data of all 29 experimental runs. In AllData.RawData_figs_1_4.run#, $t_w$, $F_{max}$, $\Delta\tilde{F}(n)$, and $d(n)$ are specified as t_w, Fmax, dFn_vec, and ds. In AllData.RawData_figs_1_4.run#.iter#, the force as a function of time can be plotted from the vectors t and F. dFn is $\Delta\tilde{F}$ of that specific iteration, and fmax is $F_{max}$ computed for that iteration. AllData.RawData_fig_2: contains the raw data of all 8 stretching periods in Fig. 2a. t_w is the time the sheet is held stretched, and t_r is the resting time during which the sheet is left unstretched, at zero force. Fmax is $F_{max}$ on every stretching cycle, and F_all and d_all are the force and displacement throughout the whole cycle. In AllData.RawData_fig_2.iter#, Fmax is the maximal and initial force in the stretching period, and Fmin is the force at the end of the stretching period. d is the displacement of the iteration, and F_t and d_t are the force and displacement recorded throughout the stretching period.
