A method of reducing the potential for repetitive stress injuries to soft tissue in performing a process, the method comprising: obtaining at least one repetitive stress data set related to the soft tissue and to the process ; accessing at least first information characterizing a first damage regime and second information characterizing a second damage regime, wherein the first information quantifies a number of repetitions at a given stress for the soft tissue to transition out of the first damage regime, and wherein the second information quantifies a number of repetitions at a given stress for the soft tissue to transition out of the second damage regime ; predicting, based on at least the first information, the second information, and the repetitive stress data set , conditions sufficient for damage to the soft tissue ; determining, based on at least the predicting, at least one guideline for reducing a risk of a soft tissue material repetitive stress injury; and implementing the at least one guideline in the process ; wherein a) the first damage regime and the second damage regime each comprise one of: a no damage regime, a sub-rupture damage regime, or a tear propagation regime; and/or b) the repetitive stress data set comprises a force over a cross sectional area of the soft tissue and at least one of a number of repetitions for, or a duration of, at least one task of the process; and/or c) the obtaining the at least one repetitive stress data set related to the soft tissue and to the process comprises estimating at least one stress distribution in the soft tissue. obtaining at least one repetitive stress data set related to the soft tissue and to the process ; accessing at least first information characterizing a first damage regime and second information characterizing a second damage regime, wherein the first information quantifies a number of repetitions at a given stress for the soft tissue to transition out of the first damage regime, and wherein the second information quantifies a number of repetitions at a given stress for the soft tissue to transition out of the second damage regime ; predicting, based on at least the first information, the second information, and the repetitive stress data set , conditions sufficient for damage to the soft tissue ; determining, based on at least the predicting, at least one guideline for reducing a risk of a soft tissue material repetitive stress injury; and implementing the at least one guideline in the process ; wherein a) the first damage regime and the second damage regime each comprise one of: a no damage regime, a sub-rupture damage regime, or a tear propagation regime; and/or b) the repetitive stress data set comprises a force over a cross sectional area of the soft tissue and at least one of a number of repetitions for, or a duration of, at least one task of the process; and/or c) the obtaining the at least one repetitive stress data set related to the soft tissue and to the process comprises estimating at least one stress distribution in the soft tissue. a) the first damage regime and the second damage regime each comprise one of: a no damage regime, a sub-rupture damage regime, or a tear propagation regime; and/or b) the repetitive stress data set comprises a force over a cross sectional area of the soft tissue and at least one of a number of repetitions for, or a duration of, at least one task of the process; and/or c) the obtaining the at least one repetitive stress data set related to the soft tissue and to the process comprises estimating at least one stress distribution in the soft tissue. <EOS>
