The Cognitive Costs of Sleep Deprivation in Ultra‐Endurance Cycling: Insights From the Race Across France

Journal of Sleep Research, EarlyView.
ABSTRACT For athletes in endurance sports, who compete over several days and in unpredictable conditions, managing sleep–wake rhythms is critical to ensure optimal performance and minimise the risks to safety. Despite its growing popularity, the role of sleep management on ultracycling performance has received little attention.

A damage-plasticity model for the dynamic failure of concrete

, 2011
A constitutive model based on the combination of damage mechanics and plasticity is developed to analyse concrete structures subjected to dynamic loading. The aim is to obtain a model, which requires input parameters with clear physical meanings.

Differential Responsiveness to Exercise and Cognitive Remediation in Physical Health in People With Schizophrenia: Results From the CORTEX‐SP Study

European Journal of Sport Science, Volume 26, Issue 6, June 2026.
ABSTRACT Non‐pharmacological interventions, such as exercise and cognitive remediation, have been widely investigated in people with schizophrenia (SZ), showing beneficial effects and supporting their role as complementary approaches to pharmacological treatment.

Capturing Complex Rate‐Dependent Behaviors of Saturated Clays: A Fractional Consistency Kinematic Hardening Viscoplastic Approach

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 8, Page 3281-3296, 10 June 2026.
ABSTRACT Saturated high plasticity clays show complex nonlinear, rate‐dependent, and hysteresis behaviors under non‐monotonic stress paths, requiring advanced mathematical constitutive equations for accurate description. Taking into account the inherent advantages of kinematic hardening mechanisms in simulating complex stress histories, this paper ...

Evolution of the Damping Ratio Considering Cyclic Confining Pressure Under Intermittent Cyclic Loading

Buildings
The damping ratio is essential to conducting dynamic analysis for underground engineering under traffic loading. Variations in the damping ratio are usually studied using cyclic triaxial tests with continuous cyclic loading; however, intermittent loading

Elastoplasticity Informed Kolmogorov–Arnold Networks Using Chebyshev Polynomials

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 8, Page 3331-3354, 10 June 2026.
ABSTRACT Multilayer perceptron (MLP) networks are predominantly used to develop data‐driven constitutive models for granular materials. They offer a compelling alternative to traditional physics‐based constitutive models in predicting non‐linear responses of these materials, for example, elastoplasticity, under various loading conditions. To attain the

The Effects of the Choice of Liquefaction Criteria on Liquefaction in Soils with Plastic Fines

J
Cyclic triaxial tests are widely used in laboratory studies to assess the liquefaction susceptibility of soils. Although standardized procedures exist for conducting these tests, there is no universally accepted criterion for defining liquefaction.

Fluid‐Driven Cohesive Strengthening: Critical Role of Reaction Kinetics as the Determinant for Frictional Stability

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Following an earthquake, faults lock and regain strength via a combination of healing mechanisms that include pressure solution, contact growth, and cementation. Fault healing dictates strength recovery during the seismic cycle and is therefore a key factor controlling earthquake recurrence intervals, stress drop, and other source properties ...

Permanent deformation characterization of bituminous mixtures: laboratorial tests [PDF]

, 2005
In the last years some laboratorial tests are used to predict the permanent deformation behaviour of bituminous mixtures. Among those tests the Wheel Tracking test, the Cyclic Compression Test (Uniaxial and Triaxial) and the Repetitive Shear at ...
