Accurate modeling of the cyclic response of structural components constructed of steel with yield plateau
(2012)A time-independent constitutive model for structural steels with a yield plateau is presented. The model is based on the basic principles of time-independent plasticity. The model couples the nonlinear kinematic hardening ... -
Constitutive Model for Cyclic Response of Structural Steels with Yield Plateau
(2011)A rate-independent cyclic plasticity model for structural steels with a yield plateau is proposed. The model couples nonlinear kinematic hardening with a memory surface in the plastic strain space, to account for the ... -
Differential expression of NMDA and AMPA receptor subunits in rat dorsal and ventral hippocampus
(2006)Several studies have demonstrated anatomical and functional segregation along the dorsoventral axis of the hippocampus. This study examined the possible differences in the AMPA and NMDA receptor subunit composition and ... -
Explicit integration of bounding surface model for the analysis of earthquake soil liquefaction
(2010)This paper presents a new plasticity model developed for the simulation of monotonic and cyclic loading of non-cohesive soils and its implementation to the commercial finite-difference code FLAC, using its User-Defined-Model ... -
Finite element analysis of discrete edge dislocations: Configurational forces and conserved integrals
(2015)We present a finite element description of Volterra dislocations using a thermal analogue and the integral representation of dislocations through stresses in the context of linear elasticity. Several analytical results are ... -
Hand preference of individuals with blindness in everyday activities: The effects of age of sight loss, age, and gender
(2014)The research aims of the present study were: (a) to assess the hand preference of blind persons in everyday activities on the basis of gender, type of blindness, and age; and (b) to conduct the above analysis at both the ... -
Insight into the seismic response of earth dams with an emphasis on seismic coefficient estimation
(2014)This paper presents a numerical investigation of the seismic response of earth dams by employing results from 110 nonlinear two-dimensional (2D) dynamic analyses of four different cross-sections with heights ranging from ... -
A Linear Complementarity formulation of rate-independent finite-strain elastoplasticity. Part II: Calculation of bifurcation and limit points
(2012)A methodology for the numerical solution of discretized boundary value problems that involve rate-independent, elastic-plastic finite-strain models is developed. The formulation is given in terms of a structural Linear ... -
Long-term exposure to muscarinic agonists decreases expression of contractile proteins and responsiveness of rabbit tracheal smooth muscle cells
(2014)Background: Chronic airway diseases, like asthma or COPD, are characterized by excessive acetylcholine release and airway remodeling. The aim of this study was to investigate the long-term effect of muscarinic agonists on ... -
Methodology for estimating seismic coefficients for performance-based design of earthdams and tall embankments
(2014)Following an overview of pertinent literature, this paper presents a new methodology for estimating seismic coefficients for the performance-based design of earth dams and tall embankments. The methodology is based on ... -
PKC-epsilon activation is required for recognition memory in the rat
(2013)Activation of PKC epsilon, an abundant and developmentally regulated PKC isoform in the brain, has been implicated in memory throughout life and across species. Yet, direct evidence for a mechanistic role for PKC epsilon ... -
Plane-Strain Problems for a Class of Gradient Elasticity Models-A Stress Function Approach
(2011)The plane strain problem is analyzed in detail for a class of isotropic, compressible, linearly elastic materials with a strain energy density function that depends on both the strain tensor epsilon and its spatial gradient ... -
Skeletal linear extension rates of the foliose scleractinian coral Merulina ampliata (Ellis & Solander, 1786) in a turbid environment
(2009)Skeletal linear extension rates of a foliaceous, IndoPacific, skiophilous, heterotrophic, scleractinian Merulina ampliata (Ellis & Solander 1786) were obtained along a sediment/nutrient load gradient at the southern islands ... -
Stability and constitutive modelling in multiphase TRIP steels
(2006)Multiphase TRIP steels are a relatively new class of steels exhibiting excellent combinations of strength and cold formability, a fact that renders them particularly attractive for automotive applications. The present work ...
