Multi‐field modeling of thermomechanical coupled fracture problems
PAMM, 2018AbstractIn this contribution we focus on a novel variationally consistent formulation for thermomechanical coupled fracture problems. To be specific, we aim on a phase‐field approach to fracture such that the resulting system consists of three fields, the deformation map, the thermal field as well as the crack phase‐field.

The temperature distribution of electrolyte in ECM affects the distribution of machining gap and the precision of forming. Considering the influence of hydrogen bubbles and electrolyte with low velocity near the wall on heat transfer, the Euler–Euler two-fluid model was used to calculate the gas volume fraction distribution and the turbulent shear ...

A MULTI-FIELD COUPLED SEEPAGE MODEL FOR COAL SEAM WITH FRACTURES OF POWER LAW LENGTH DISTRIBUTIONS
Fractals, 2021In the process of gas mining, the fracture distribution with power law length and the pore structure with adsorption effect have an important influence on the coal seam permeability. In recent years, the research on the internal structure of coal seam and the fluid flow mechanism has attracted a large number of researchers.
