Abstract This study presents a model for Ti6Al4V alloy produced by applying electron beam melting as continuum media with orthotropic elastic and plastic properties its application in total hip replacement (THR). The exhibits three Young’s moduli, shear Poisson’s ratios six coefficients describing the Hill yield criterion. Several uniaxial tension torsion experiments subsequent data processing ...

Abstract The grain structure and texture of additively manufactured materials depend strongly on the local temperature gradients during solidification material. These structures textures influence mechanical behavior, ranging from isotropy to transversal orthotropic symmetry. In present contribution, a cellular automaton is used model growth selective electron beam melting. resulting serve as i...

In complex task domains, such as games, students may exceed their teachers. Such tasks afford diverse means to tradeoff one type of performance for another, combining task elements in novel ways to yield method variations and strategy discoveries that, if mastered, might produce large or small leaps in performance. For the researcher interested in the development of extreme expertise in the wil...

1. Abstract Composite plates are designed in order to maximize the performance with respect to eigenfrequencies. The plates are considered to be laminates where the individual plies consist of orthotropic material. The design task is the orientation of the orthotropic material in each element of the discretization and the ratio between the amounts of material put in the two directions of the fi...

In contrast to conventionally-produced structural steel and stainless elements, wire arc additively manufactured (WAAM) elements can exhibit a strongly anisotropic material response. To investigate this behaviour, data obtained from tensile tests on machined as-built coupons extracted WAAM sheets are analysed. The observed mechanical response in the elastic range is described accurately using a...

The stability of the finite-difference approximation of elastic wave propagation in orthotropic homogeneous media in the three-dimensional case is discussed. The model applies second- and fourth-order finite-difference approaches with staggered grid and stress-free boundary conditions in the space domain and second-order finite-difference approach in the time domain. The numerical integration o...

Accurately modeling the material behavior of paper and paperboard is proven to be highly demanding. Most difficulties arise from pronounced anisotropic nature material. Additionally, differences in in-plane out-of-plane as well non-isochoric plasticity, which affects elastic behavior, further deepen issue at hand. Therefore, an model proposed, capable capturing elasto-plastic paperboard. The co...

In this paper, a fiber Bragg grating (FBG)-based stress monitoring system instrumented on an orthotropic steel deck arch bridge is demonstrated. The FBG sensors are installed at two types of critical fatigue-prone welded joints to measure the strain and temperature signals. A total of 64 FBG sensors are deployed around the rib-to-deck and rib-to-diagram areas at the mid-span and quarter-span of...
