Stability analysis of a glulam dome with nonlinear material law
… of this study is to incorporate a nonlinear material law for wood in the finite element program ABAQUS to develop effective finite element models of glulam domes, and to investigate the buckling behavior of glulam domes using this finite element program. The material law is implemented with a …

Größeneinflüsse beim mechanischen Verhalten von Wolfram,Kupfer-Teilchenverbundwerkstoffen
… quasi-static flow curves were described with the material law from Swift. The parameters of the material law were presented as a function of the temperature and the specimen size. The mechanical behaviour of the composite materials were numerically computed for an idealized axis-symmetric …

Nonlinear 3-D beam/connector finite element with warping for a glulam dome
… of variation in parameters such as the nonlinear material law and the stiffness of hinge-connector elements on the dome cap model is examined. A dome cap model with 16 nailed joints for each beam is analyzed. Dome models with nailed joints at truss bracing points (i.e., the end nodes of the truss …

Computational and experimental modelling of the crushing of prepared sugar cane
… the computational models. For isotropic plastic material behaviour, constitutive models that represent yielding under hydrostatic pressures are applied. The constitutive behaviour of the solid skeleton, and the plastic strain hardening response are derived from a series of slow speed confined …

Development and Application of Low-Order Computational Models of the Left Ventricle
… in a mouse model. We assume the "Guccione law," a four parameter transversely isotropic material law, for the elastic properties of the myocardium. The stiffness parameters are estimated using two objective functions: a displacement objective and an aggregated objective. We find that the …

Dynamisches Mehrphasenmodell mit hypoplastischer Materialformulierung der Feststoffphase
The numerical simulation of heterogeneous materials with solid and pore filling fluid phases becomes more and more important in different areas of engineering practice due to the availability of high performance computers. The classical application area of multiphase models is the investigation of …

Untersuchung des Aufrauungsverhaltens von Reinaluminium bei Walz- und Zugverformung
The surface topography of a bulk material is not only responsible for its optical appearance; it also has a strong influence on its physical properties like tensile strength or corrosion resistance. The topography develops during deformation due to extrinsic effects like tool-contact or due to …

Computational modelling of ice floe dynamics in the Antarctic marginal ice zone.
… detailed model implies a heterogeneous sea ice material composition, considering separately ice floes and grease ice with their distinct properties. The material behaviour of ice floes is implemented using a Hookean-like flow rule, whereas grease ice is governed by a viscous-plastic material …

… 2 paragraph (2) and Article 43 paragraph (1) of Law no. 1/1974. In the applicant's request, the two articles are considered contrary to Article 28B paragraph (1) and paragraph (2) and Article 28D paragraph (1) of the 1945 Constitution. Based on the the material law above, then the formulation of …

Multistable Shell Structures
… In a second step, a polar-orthotropic material law is employed to study variations of the directional stiffness of the shell itself. A careful choice of the basis functions is required to accurately capture stress singularities in bending that arise if the radial Young’s modulus is …
