“…To predict the initiation of damage in the welded areas, specifically in the cohesive zone, the quadratic traction initiation criterion was employed. This criterion, ex-Polymers 2023, 15, 3555 10 of 18 pressed mathematically as follows, enables the determination of the critical conditions for damage initiation [38]:…”

Ultrasonic welding technology represents an advanced method for joining thermoplastic composites. However, there exists a scarcity of systematic investigations into welding parameters and their influence on the morphological characteristics and quality of the welded regions. Furthermore, a comprehensive experimental understanding of the welded joint failure mechanisms remains deficient. A robust model for simulating the failure behavior of welded joints under loading has yet to be formulated. In this study, ultrasonic welded specimens were fabricated using distinct welding control methods and varied parameter combinations. Diverse experimental methodologies are employed to assess the morphological features of the welded areas, ascertain specimen strength, and observe welding interface failure modes. Based on a cohesive model, a finite element model is developed to predict the strength of the ultrasonic welded joints and elucidate the failure mechanisms. The results showed that, under identical welding parameters, the specimens welded with a high amplitude and low welding force exhibit superior welding quality. The specimens produced under displacement control exhibit minimal dispersion in strength. The proposed finite element model effectively prognosticates both welded joint strength and failure modes.

Summary Multicomponent multiphase fluid flows are commonly seen in the engineering practice of hydrocarbon production and transportation; thus, the phase‐wise heat and mass transfer mechanisms underneath the macroscopic flow and transport behaviors are essentially needed for better understanding of the physical phenomena and optimization of the industrial processes. Flash calculation, as the main approach computing phase equilibrium conditions, has arisen increasing interests to establish the thermodynamic foundations of multiphase flow simulation, as well as to determine whether two‐phase model is needed. In this paper, the general thermodynamically‐consistent flash calculation scheme will be developed, and the general adaptability to various special mechanisms will be analyzed. A unified framework of thermodynamics‐informed neural network will also be designed to accelerate conventional iterative flash calculation schemes that will be applied in various engineering scenarios to provide certain suggestions to the energy industry based on the predictions and analysis. Novelty Statement A thermodynamically‐consistent flash calculation scheme incorporating various special mechanisms that are often met in energy industry. A unified thermodynamics‐informed neural network structure for various engineering demands in the energy industry. Suggestions to the energy industry to optimize the productions based on the phase transition predictions and analysis.

“…These sequences are then subjected to macroscopic delamination tests, in order to evaluate the effect of this pre-cracking on the interface tenacity. Secondly, a modeling approach is proposed, based on a new type of interface model [3]. Unlike the classical cohesive elements, which only consider the out-of-plane part of the displacement jump at the interface, our hybrid model also uses the planar part of the displacement jumps.…”
