Predicting resilient modulus: A data driven approach integrating physical and numerical techniques

Heliyon
Resilient modulus (MR) is an important parameter in the design of pavement that helps to characterize the quality of sub-grade materials. Generally, it is not determined experimentally due to time consuming, uneconomical, laborious and lack of advanced ...

An Elasto–Plastic Hydro–Mechanical Model for Analyzing the Swelling Behavior of Heterogeneous Clay–Sulfate Rocks

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Swelling of clay‐sulfate rocks is a concern in geotechnical engineering that can damage infrastructure. In the historic town of Staufen in southwest Germany, geothermal drilling into a swellable anhydrite‐bearing clay formation resulted in water inflow and subsequent swelling, triggering ground heave and damage to more than 250 houses.

Hypoplastic Model for Unsaturated Soils With Degree of Saturation Dependent Stiffness

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This paper presents an enhanced hydro‐mechanically coupled hypoplastic constitutive model for unsaturated soils, developed by extending an existing framework, with particular emphasis on improving the stiffness formulation to better capture the influence of the degree of saturation. The existing framework links Bishop's effective stress to the

Toward the Application of Multiaxial Failure Criteria: Mean Stress Sensitivity of Carbide‐Rich, High‐Alloy PM‐HIP Tool Steels Under Axial and Torsional Cyclic Loading

steel research international, EarlyView.
This study quantifies axial and torsional long‐life fatigue (LLF) behavior of three carbide‐rich PM‐HIP tool steels, correlating LLF strength with intrinsic defect size and cleanliness, thereby extracting material‐specific mean stress sensitivities and Haigh diagrams.

Effect of Double Annealing on the Microstructure and Mechanical Properties of a Medium Manganese Steel

steel research international, EarlyView.
A double intercritical annealing strategy is proposed to tailor the multiphase microstructure and mechanical response of a medium‐Mn steel. The treatment produces an ultrafine mixture of ferrite, martensite and multiple austenite populations with graded thermal and mechanical stability, formed through austenite reversion and controlled retransformation.

Damage Investigation of the Preform Operations for the Production of Rings for Ring Rolling

steel research international, EarlyView.
Void evolution during the preforming operations of two industrial ring rolling process routes is investigated by combining metallographic characterization with a two‐scale finite element simulation approach. The results reveal that, despite differing initial void conditions, the preforming operations can be designed to effectively influence void ...

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

Structural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Effect of true triaxial principal stress unloading rate on strain energy density of sandstone

Scientific Reports
Deep rock are often in a true triaxial stress state. Studying the impacts of varying unloading speeds on their strain energy (SE) density is highly significant for predicting rock stability.
