Construction and finite element simulation of a square laser loading model that can replace circular spot superposition in laser peening forming

Journal of Advanced Mechanical Design, Systems, and Manufacturing
In order to explore an efficient, accurate, and convenient finite element simulation method for laser peening forming, a square laser loading model was constructed by studying the loading feature unit of the circular spot superposition model, which can ...

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

Advanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.

A finite element model updating method for aqueduct structures based on Bayesian theory

Shuili Shuiyun Gongcheng Xuebao
The structural condition of aqueducts changes over time due to various influencing factors. Consequently, parameters used in finite element analysis may not reflect the real-time state of the structure.

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

A Composite Finite Element-Finite Difference Model Applied to Turbulence Modelling [PDF]

, 2007
Turbulence has been modeled by a two equation k-?turbulence model to investigate the wind induced circulation patterns in coastal waters. Predictions of the model have been compared by the predictions of two equation k-?turbulence model. Kinetic energy of turbulence is k, dissipation rate of turbulence is ?, and frequency of turbulence is ?.
