Phase field method for quasi-static hydro-fracture in porous media under stress boundary condition considering the effect of initial stress field
Shuwei Zhou, Xiaoying Zhuang, Timon Rabczuk
Phase field model (PFM) is an efficient fracture modeling method and has high potential for hydraulic fracturing (HF). However, the current PFMs in HF do not consider well the effe…
Polytopal composite finite elements for modeling concrete fracture based on nonlocal damage models
Hai D. Huynh, S. Natarajan, H. Nguyen-Xuan +1
The paper presents an assumed strain formulation over polygonal meshes to accurately evaluate the strain fields in nonlocal damage models. An assume strained technique based on the…
Phase field modeling of brittle compressive-shear fractures in rock-like materials: A new driving force and a hybrid formulation
Shuwei Zhou, Xiaoying Zhuang, Timon Rabczuk
Compressive-shear fracture is commonly observed in rock-like materials. However, this fracture type cannot be captured by current phase field models (PFMs), which have been proven…
Variational energy based XPINNs for phase field analysis in brittle fracture
Ayan Chakraborty, Cosmin Anitescu, Somdatta Goswami +2
Modeling fracture is computationally expensive even in computational simulations of two-dimensional problems. Hence, scaling up the available approaches to be directly applied to l…
A micropolar peridynamics model with non-unified horizon for damage of solids with different non-local effects
Yiming Zhang, Xueqing Yang, Xiaoying Zhuang
Most peridynamics models adopt regular point distribution and unified horizon, limiting their flexibility and engineering applications. In this work, a micropolar peridynamics appr…
Three-dimensional topology optimization of auxetic metamaterial using isogeometric analysis and model order reduction
Chuong Nguyen, Xiaoying Zhuang, Ludovic Chamoin +3
In this work, we present an efficiently computational approach for designing material micro-structures by means of topology optimization. The central idea relies on using the isoge…
