,Divergence Free VEM for the Stokes Problem with No Internal Degrees of Freedom, the same authors for the Navier-Stokes equation, here focusing on the simpler Stokes problem. The basic advantage of the method is, in addition to the capability of handling general polytopal meshes, the property of delivering a truly divergence-free velocity solution. In addition, it exists a redu

Strategy for Preventing Membrane Locking Through Reparametrization,n. After briefly summarizing the successful concept for avoiding transverse shear locking through reparametrization of primary variables for beams, plates and shells we concentrate on the same approach for preventing also membrane locking. Here, we describe first steps referring to the plane curved

Model-Free Fracture Mechanics and Fatigue,of discrete data points encoding the information about the material behavior, thus the fracture-related modeling assumptions are completely removed. The solution at a given load step is identified as the point within the data set that best satisfies equilibrium and compatibility conditions stemming

,Node Based Non-invasive Form Finding Revisited—The Challenge of Remeshing,sents the finished part. In order to keep the subsequent finishing steps of the manufactured component to a minimum, the aim is to produce the finished part within small geometric tolerances. Thereby, a predefined target configuration defines the optimal shape of the part. Here, non-invasive form fi

,Experimental and Numerical Investigation of Granules as Crash-Absorber in Ship Building,construction. The granular material is filled into the cavity between the two hull layers in order to increase the safety in the event of a collision of the ship with another vessel. The benefit of the filling material is twofold. First of all it helps to carry the load from the outer hull to the in

,On Hydraulic Fracturing in Fully and Partially Saturated Brittle Porous Material, exploitation of oil and natural gas, for geothermal purposes and further applications. Although fracking techniques are widely used in practice, they are scientifically not well established. This is due to the fact that the underground is a complicated matter made of rock or soil filled with fluids

Efficient Two-Scale Modeling of Porous Media Using Numerical Model Reduction with Fully Computable on. Thereby, the displacement and pore pressure are the unknown fields. A suitable reduced basis is constructed for the pore pressure approximation using Proper Orthogonal Decomposition (POD), whereby it is possible to compute the appropriate basis for the displacement field in the spirit of Nonline
