Numerical simulation study on the characteristics and propagation attenuation of vibration signals in freezing pipe fracture

Deep Underground Science and Engineering, EarlyView.
This research study employs analysis system (ANSYS) fluid–structure interaction simulations to investigate the generation and attenuation of vibration signals resulting from freezing pipe fractures in artificial ground freezing projects. By evaluating key variables—including frozen soil elastic modulus, brine inlet pressure, and external pipe pressure ...

Seismic Performance of Reduced‐Strength Steel MRFs With SMA‐Based Superelastic Friction Dampers: An Experimental Investigation

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Shape memory alloys (SMAs) exhibit excellent self‐centering capability due to their stress‐induced phase transformation, making them highly suitable for applications in resilient infrastructure. This study investigates the seismic performance of reduced‐strength moment‐resisting frames (MRFs) equipped with SMA‐based superelastic friction ...

Experimental Study on the Lateral Response of Large‐Scale Unbonded Steel‐Mesh‐Reinforced Rubber Bearings

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Conventional unbonded elastomeric bearings (ULNRs) are cost‐effective but prone to sliding during earthquakes due to their limited shear deformability. Unbonded Steel‐Mesh‐Reinforced Rubber Bearings (USRBs) offer a solution with increased deformation capacity.

Study on Fluid Pressure in Tubing, Dynamic Stress in Reservoir, and Fracture Propagation Morphology During Variable‐Rate Hydraulic Fracturing

Energy Science &Engineering, EarlyView.
Variable‐rate hydraulic fracturing can induce unsteady flow in the tubing, thereby generating fluctuating fluid pressure near the bottom‐hole reservoir. Dynamic stress is generated in the reservoir under the action of fluctuating fluid pressure and propagates as stress waves.

Analysis of cross-ply laminated plates using isogeometric analysis and unified formulation

Curved and Layered Structures, 2014
In this paper, we study the static bending and free vibration of cross-ply laminated composite plates using sinusoidal deformation theory. The plate kinematics is based on the recently proposed Carrera Unified Formulation (CUF), and the field variables ...
