Phase field method for simulating the brittle fracture of fiber reinforced composites

Engineering Fracture Mechanics, 2019
We implemented a three-dimensional phase field model to simulate crack initiation and propagation in fiber reinforced composites. An efficient and robust staggered scheme is adopted by decoupling the fracturing phase field and displacement field.

The Phase-Field Method in Optimal Design

2006
We describe the phase-field method, a new approach to optimal design originally introduced in Bourdin and Chambolle (2000, 2003). It is based on the penalization of the variation of the properties of the designs, and its variational approximation (in the sense of Г-convergence.

Robust topology optimization of vibrating structures considering random diffuse regions via a phase-field method

Computer Methods in Applied Mechanics and Engineering, 2019
This paper investigates a robust topology optimization method for structural dynamic problems by considering random diffuse-region widths between different material phases using a phase-field model.

Bone Remodeling from the Perspective of the Phase Field Method

2019
In this work, we have developed a mechanobiological model of bone remodeling involving a mineralization of bone in a moving diffuse interface separating the marrow containing all specialized cells from newly formed bone. The phase field describes the degree of mineralization within the diffuse interface at the level of individual trabeculae; it varies ...
