Nonlinear equations of ribbed shells balance taking into account the different properties of material [PDF]

open access: yesИнженерно-строительный журнал, 2010
In previous works isotropic and orthotropic shells of general form, under the influence of static and dynamic mechanical loads in conditions of elastic, nonlinear elastic and viscoelastic properties of the material development were considered.It was ...

Maximum dynamic stress on bridges traversed by moving loads

open access: yes, 2009
Most current research on dynamic effects due to traffic load on simply supported bridges focuses on the mid-span section of the bridge, since this location corresponds to the worst static bending moment.

Mechanistic–Empirical Analysis of Pavement Performance Considering Dynamic Axle Load Spectra Due to Longitudinal Unevenness

open access: yesApplied Sciences, 2022
Pavement distresses are induced by mechanistic responses in pavement structure subjected to dynamic loads of moving vehicles. Pavement surface evenness deteriorates as pavement distresses propagate, which results in dynamic axle loads and faster pavement

Resistance of reinforced concrete beams in explosive charges [PDF]

open access: yesBiuletyn Wojskowej Akademii Technicznej, 2016
The paper presents an analysis of the dynamic interaction on reinforced concrete beams, caused by the outbreak of not-direct contact with the design. Depending on the distance of the source of the outbreak, the structure may be loaded with gas stream ...

Evaluation of dynamic loads on a skew box girder continuous bridge - Part II: Parametric study and dynamic load factor

open access: yes, 2007
Studies on dynamic loads are important for bridge engineering as well as pavement design. A large number of research studies have indicated that bridge dynamic loads increase road surface damage by a factor of 2-4.

Time Toxicity in Wilms Tumor: Quantifying the Burden of Healthcare Interaction in the First Year After Diagnosis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Wilms tumor (WT) treatment imposes a significant time burden on patients and their families. Time toxicity is a patient‐centered metric that quantifies the burden of healthcare interaction. We sought to define time toxicity in the first year after diagnosis of WT and hypothesized that it would increase as tumor stage and treatment ...

Using Light-Gas Guns in Testing the Strength of Solid Gun Propellant Grains [PDF]

open access: yesProblemy Mechatroniki
NATO Standardisation Agreements (STANAGs) 4241 and 4496 outline destructive testing procedures to determine how gun propellants in artillery munitions behave when struck by a 12.7 × 99 mm anti-tank projectile travelling at approximately 850 m/s, or by a ...
