Constitutive model for the finite deformation stress–strain behavior of poly(ethylene terephthalate) above the glass transition
Abstract A constitutive model for the finite deformation stress–strain behavior of poly(ethylene terephthalate) (PET) at temperatures above the glass transition temperature is presented. In thisExpand
Biomechanics of brain tissue.
The proposed constitutive framework was found to be adequate to model the loading response of brain tissue in uniaxial compression over a wider range of strain rates, thereby providing a valuable tool for simulations of dynamic transients (impact, blast/shock wave propagation) leading to traumatic brain injury.

Mechanical and biochemical properties of human cervical tissue.
Investigation of the mechanical and biochemical properties of cervical samples from human hysterectomy specimens indicates that cervical stroma has a nonlinear, time-dependent stress response with varying degrees of conditioning and hysteresis depending on its obstetric background. Expand
Micromechanics of toughened polycarbonate
Abstract Numerical studies are presented on micromechanical and macromechanical aspects of deformation mechanisms in toughened polycarbonate. The dependence of the macroscopic stress–strain behavior,Expand
Relationships between mechanical properties and extracellular matrix constituents of the cervical stroma during pregnancy.
An improved understanding of the biochemistry of cervical "strength" will shed light on how the cervix maintains its shape in normal pregnancy and shortens in preterm birth. Expand
A study of the anisotropy and tension/compression behavior of human cervical tissue.
The results presented in this study suggest that cervical tissue is mechanically anisotropic with a uniaxial response dependent on the direction of loading, the anatomical site of the specimen, and the obstetric history of the patient. Expand
A viscoelastic, viscoplastic model of cortical bone valid at low and high strain rates.
A new viscoelastic, viscoplastic constitutive model is proposed which is fitted to three sets of stress-strain measurements from the literature and shown to be valid at strain rates ranging over seven orders of magnitude. Expand
Changes in the biochemical constituents and morphologic appearance of the human cervical stroma during pregnancy.
Investigating the biochemical and morphological changes in cervical stroma associated with physiological remodeling during normal pregnancy found significant changes were seen in the concentration and organization of cervical ECM constituents duringnormal pregnancy. Expand
Dynamic mechanical response of brain tissue in indentation in vivo, in situ and in vitro.
The consistent, quantitative set of mechanical measurements thereby collected provides a preliminary experimental database, which may be used to support the development of constitutive models for the study of mechanically mediated pathways leading to traumatic brain injury. Expand
Numerical determination of the elastic driving force for directional coarsening in Ni-superalloys
Abstract We have developed a general methodology, in the framework of the finite element method, for locally evaluating the generalized force acting on a material interface which is work-conjugateExpand
