Application of the p-version of the finite element method to elastoplasticity with localization of deformation
(1999)In this paper we discuss the use of the p-version of the finite element method applied to elastoplastic problems that exhibit sharp (but continuous) deformation gradients. The deformation theory of deviatoric, linearly ...

Determining true material constants of semisolid slurries from rotational rheometer data
(2016)In this work we revisit the issue of obtaining true material constants for semisolid slurries. Therefore, we consider the circular Couette flow of Herschel-Bulkley fluids. We first show how true constants can be obtained ...

Double Networks Based on Amphiphilic Cross-Linked Star Block Copolymer First Conetworks and Randomly Cross-Linked Hydrophilic Second Networks
(2016)This study presents the preparation and characterization of double networks (DN) based on a first amphiphilic polymethacrylate conetwork (APCN) and a second polyacrylamide network. The APCN first network comprised ...

Double-networks based on pH-responsive, amphiphilic "core-first" star first polymer conetworks prepared by sequential RAFT polymerization
(2017)This manuscript presents the preparation and study of a new double-network hydrogel system, comprising an amphiphilic, pH-responsive first polymer conetwork synthesized via reversible addition-fragmentation chain transfer ...

Geometrically strained carbenes: Interdependence among geometry, spin multiplicity and reactivity
(2001)The singlet and triplet states of cyclobutenylidene 1 and benzocyclobutenylidene 2 have been studied computationally (using ab initio and DFT methods) in order to assess the effect of angle strain on the S-T gap of vinyl- ...

A mechanistic approach in defining inelastic rotation capacity of RC columns
(National Technical University of Athens, 2017)When a reinforced concrete (RC) column is subjected to lateral sway as a result of earthquake action, the large strain demand in the end sections is supported by development of strains in the anchorage. This causes the ...

On shear deformable beam theories: The frequency and normal mode equations of the homogeneous orthotropic bickford beam
(2001)This paper provides a step forwards the construction and documentation of the frequency equations and the characteristic functions of a general three-degrees-of-freedom theory that describes the plane motion of shear ...

Synthesis and characterization of robust double-networks based on end-linked, pH-responsive first networks
(2015)Abstract Fragile, end-linked hydrophilic tertiary amine based methacrylate (first) networks were mechanically reinforced using the double-network principle, via the introduction of a polyacrylamide second network. Reinforcement ...

Uniaxial and biaxial mechanical behavior of human amnion
(2005)Chorioamnion, the membrane surrounding a fetus during gestation, is a structural soft tissue critical for maintaining a successful pregnancy and delivery. However, the mechanical behavior of this tissue membrane is poorly ...
