“…COMSOL Multiphysics [10] is a finite element multi-physics field numerical analysis software with arbitrary independent functions to control the solution parameters such as material properties [11], boundary conditions, loads and other parameters, as well as powerful mesh dissection capabilities. While phenomena simulated by the finite element method often originate in traditionally separate fields of applied physics and engineering, the method is also widely used in the food sector, mainly for drying and processing, storage and preservation of food products, simulation of temperature and humidity fields, etc.…”

As a traditional Chinese dish cutting technology process, Gaidao artificially create cuts embedded in the food surface by cutting through it with knife, a process that currently plays an important role in the beef marinating process. And different Gaidao processes directly affect the beef marination flavour and marination efficiency. This study is the first to propose the use of Hyperspectral imaging technology (HSI) combined with finite element analysis to investigate the effect of Gaidao process on the quality of marinated beef. The study was carried out by collecting spectral information of beef marinated with different sucrose concentrations and combining various pre-processing methods and algorithms such as PLS, BiPLS, iPLS, and SiPLS to establish a quantitative model of sucrose concentration in beef, and finally optimizing parameters such as the length, position and number of Gaidao by Finite Element Analysis (FEA), which showed that when marinated with 1.0 mol/m³ sucrose solution, the concentration of sucrose in all tissues in the Gaidao steak reached 0.8 mol/m³ and above, which greatly improved the diffusion effect of the marinade. This work provides new ideas and methods to optimize the beef marinade Gaidao process, which has important practical value and research significance.

“…Patil et al (2018) proposed a multiscale phase field method to simulate the damage onset and propagation in the composite materials based on the multiscale finite element method with the phase field method. Sarkar et al (2020) studied the fracture with consideration of coupled thermomechanical effect by the gradient damage mechanics model, and then combined the extended finite element method and gradient continuum damage to get benefits from both methods (Sarkar et al, 2021), and also introduced the implementation in COMSOL (Sarkar et al, 2022b). The gradientbased method can also be applied to ductile damage development; see (Sarkar et al, 2022a).…”

This paper proposes an algorithm to evaluate dissipation energy of an isotropic continuum damage mechanics model with an adaptive time-step control approach. The algorithm takes place at each integration point under the scope of finite element analysis. The total amount of the dissipation energy of one structure can be used to verify the conservation law of energy, where the summation of the elastic strain energy and the dissipation energy should be equal to the total work by external force. However, the paper shows that this condition may not be valid when the unstable crack propagation occurs. When the crack propagation is unstable, the development of damage can be driven by stored strain energy without external load. The strains at the beginning and ending time within one increment at the damaged elements will give inaccurate dissipation energy by the classic trapezoidal integration scheme. In addition, this paper proposes a new damage evolution shape function with C1 continuity of the strain-stress curve under the uniaxial tension test, which is used to demonstrate the numerical procedure of the adaptive algorithm.
