3D finite element simulations of reinforced concrete elements exposed to fire [PDF]

open access: yes, 2017
Fire could dramatically reduce strength of reinforced concrete elements and it is considered one of the major threats for the structural safety of buildings: structural members may even collapse due to intensity and duration of fire.

Моделювання процесів повзучості на основі нелінійної теорії в’язкопружності із незалежною від часу нелінійністю [PDF]

open access: yes, 2010
Розглянуто задачу побудови одновимірних визначальних рівнянь нелінійної теорії в‘язкопружності. Розв’язок отримано на підставі гіпотези єдиної діаграми деформування, виходячи із подібності ізохронних діаграм повзучості та діаграми миттєвого ...

A thermodynamic framework to develop rate-type models for fluids without instantaneous elasticity

open access: yes, 2010
In this paper, we apply the thermodynamic framework recently put into place by Rajagopal and co-workers, to develop rate-type models for viscoelastic fluids which do not possess instantaneous elasticity.

Constitutive response of Rene 80 under thermal mechanical loads [PDF]

open access: yes
The applicability of a classical constitutive model for stress-strain analysis of a nickel base superalloy, Rene' 80, in the gas turbine thermomechanical fatigue (TMF) environment is examined.

The development of creep damage constitutive equations for low Cr-Mo alloy steel and its weldment at low stress [PDF]

open access: yes, 2013
The ultimate objective of this research project is to develop creep damage constitutive equations for low Cr-Mo alloy and its weldment under low stress (0.2-0.4 yield stress,σ_Y).

RESEARCH ON CREEP TEST AND CONSTITUTIVE MODEL COMPARISON OF COMРАСTED GRAPHITE CAST IRON UNDER WIDE TEMPERATURE AND STRESS RANGE

open access: yesJixie qiangdu
As the power density of an engine increases, so does the temperature and stress that the cylinder head is subjected to during operation. Therefore, creep damage prediction needs to consider accurate creep constitutive models and parameters.

Unified Viscoplastic Behavior of Metal Matrix Composites [PDF]

open access: yes
The need for unified constitutive models was recognized more than a decade ago in the results of phenomenological tests on monolithic metals that exhibited strong creep-plasticity interaction.
