Punching shear of unbonded post‐tensioned steel fiber reinforced concrete slabs: The fiber contribution

Structural Concrete, EarlyView.
Abstract Steel fiber reinforced concrete (SFRC) enhances the flexural capacity of flat slabs and, due to its effectiveness in statically redundant bi‐dimensional elements, represents a viable alternative to conventional reinforcement. Although numerous studies have investigated the flexural behavior of SFRC slabs with and without bonded reinforcement ...

Investigation of the failure characteristics of fissure tunnels under dynamic and static combinations

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 43-55, March 2026.
This article aims to investigate the dynamic fracture response of fractured tunnel models under zero geological stress through physical experiments and numerical simulations. It further simulates the dynamic fracture characteristics of fractured tunnel models under geological stress ranging from 0 to 2.5 MPa using the numerical software AUTODYN ...

Compaction of agricultural and forest subsoils by tracked heavy construction machinery

, 2004
Precompression stress has been proposed as a criterion for subsoil compression sensitivity in regulations, limiting mechanical loads by vehicles, trafficking on agricultural and forest soils.

In search of a sound scientific basis for quantification of soil precompression stress

Soil Science Society of America Journal
Abstract Soil compaction is a serious threat to soil functions and ecosystem services. Persistent soil deformation takes place when mechanical stress exceeds soil strength. Risk assessment models typically assume soil to be elastic to a precompression stress level and plastic above this threshold.

From Origami to Bistable and Laminate Structures: A Review for Multifunctional Applications from Structural Perspective of Shape‐Changing Structures

Advanced Intelligent Systems, Volume 8, Issue 2, February 2026.
This review explores how shape‐changing structures—origami, bistable, and laminate structures—enable multifunctionality in soft robotics and metamaterials. Starting from structural design, it examines core principles, real‐world applications, and ongoing challenges.

Nonadiabatic and Anharmonic Effects in High‐Pressure H3S and D3S Superconductors

Annalen der Physik, Volume 538, Issue 1, January 2026.
Superconductivity in high‐pressure H3S${\rm H}_3{\rm S}$ and D3S${\rm D}_3{\rm S}$ is studied using first‐principles calculations that include anharmonic lattice dynamics and nonadiabatic electron‐phonon vertex corrections, going beyond the conventional Migdal‐Eliashberg framework. These effects suppress the effective electron–phonon coupling and lower

The influence of soil gravel content on compaction behaviour and pre-compression stress

, 2013
Many arable soils have significant horizon-specific gravel content levels. Just how these influence compaction behaviour, and in particular precompression stress as an important criterion of a soil's susceptibility to compaction, has yet to be ...

Efficiency of Encapsulated Probiotic Consortia in the Modulation of Microbiota and Immunity of Cultured Marine Shrimp (Penaeus vannamei)

Aquaculture Research, Volume 2026, Issue 1, 2026.
Aquaculture faces significant challenges due to bacterial and viral disease outbreaks, such as white spot syndrome (WSSV) and vibriosis, which cause substantial economic losses. As an alternative to conventional antimicrobials, this study evaluated the efficacy of probiotic consortia encapsulated in calcium alginate in modulating the intestinal ...

Respiratory Function, Muscle Biomechanics, and Pain Sensitivity in Individuals With Bruxism

International Journal of Clinical Practice, Volume 2026, Issue 1, 2026.
Background Bruxism is a multifactorial condition characterized by repetitive masticatory muscle activity that may influence not only the stomatognathic system but also cervical muscle biomechanics and respiratory function. This study aimed to investigate pulmonary function, biomechanical properties, and pressure pain sensitivity of the masticatory and ...

Past consolidation stress estimates in cretaceous clay

, 1984
It is shown in this paper that in a highly overconsolidated undis turbed clay, due to natural unloading, most of the strain was recovered in the vertical direction, but not in the horizontal direction.
