Activation of a muscle as a mapping of stress–strain curves [PDF]
Extreme Mechanics Letters, 2019 The mathematical modeling of the contraction of a muscle is a crucial problem in biomechanics. Several different models of muscle activation exist in literature. A possible approach to contractility is the so-called active strain: it is based on a multiplicative decomposition of the deformation gradient into an active contribution, accounting for the ...
