Crack Propagation of SS304/BNi-2 Brazed Joints: Experiments and Numerical Simulations

Metals, 2019
The strength of brazed joints is of great significance for plate-fin heat exchangers. Although a lot of research on the strength of brazed joints has been carried out, few studies have focused on the whole process of the crack propagation of brazed ...

A new cohesive-based modelling of moisture-dependent mode II delamination of carbon/epoxy composites

Journal of Materials Research and Technology
The cohesive zone model (CZM) is widely employed for simulating delamination and debonding behaviour in engineering structures. However, the choice of CZM shape impacts the accuracy of simulation results.

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

New Approach to Evaluate Joint Delamination Mechanism of Divertor by Finite Element Analysis Applying Cohesive Zone Model (CZM); Parametric Study on the Maximum Traction under Heating

Plasma and Fusion Research
To evaluate the delamination mechanism of the joint interfaces of a plasma-facing component, a new approach using the finite element analysis (FEA) applying the cohesive zone model (CZM) is proposed. The parametric study on the maximum traction τmax, which is one of the principal CZM parameters, was conducted for compensating the lack of material data.

Stability Evaluation and Parametric Optimization of Coal‐Concrete Composite Bearing Systems Under Mine‐Water‐Induced Deterioration: Experiments and FEINN Analysis

Energy Science &Engineering, EarlyView.
Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...
