New nonlinear stress-strain model for loess and its comparative research

open access: yesYantu gongcheng xuebao, 2017
At present, the stress-strain curve of loess can only be described by using different mathematical models according to its morphological type. To achieve a unified description of the stress-strain mathematical model, a new nonlinear model is proposed ...

Activation of a muscle as a mapping of stress–strain curves [PDF]

open access: yesExtreme 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 ...

Correlation between Engineering Stress-Strain and True Stress-Strain Curve [PDF]

open access: yesAmerican Journal of Civil Engineering and Architecture, 2014
The most commonly accepted method in evaluation of the mechanical properties of metals would be the tension test. Its main objective would be to determine the properties relevant to the elastic design of machines and structures. Investigation of the engineering and true Stress-strain relationships of three specimens in conformance with ASTM E 8 - 04 is
