In this paper, an anisotropic ductile fracture is studied using a phase-field model. This model is on the basis of the energy principle in which a scalar field is added as a phase-field variable to determine the probability paths of cracks. Therefore

In this work, brittle fracture and thermo-mechanical induced cracks are simulated using a phase field model in 2D and 3D continua in homogeneous and heterogeneous materials. The phase field model for fracture has specific regulations regarding the fi

An adaptive finite element simulation was developed to predict fretting wear in a head-neck taper junction of hip joint implant through a two dimensional (2D) model and based on the Archard wear equation. This model represents the most critical secti

The impaction force required to assemble the head and stem components of hip implants is proven to play a major role in the mechanics of the taper junction. However, it is not clear if the assembly force could have an effect on fretting wear, which n

In this paper, a thermodynamically consistent formulation and numerical implementation of a gradient-enhanced anisotropic microplane damage model are proposed. The microplane model is derived based on the volumetric–deviatoric split and the kinemat

In this paper, a gradient-enhanced 3-D phenomenological model for shape memory alloys using the non-local theory is developed based on a 1-D constitutive model. The method utilizes a non-local field variable in its constitutive framework with an impl
