Trigger for the occurrence of grain coarsening phenomenon of BS304S31 austenite stainless steel under small plastic strain at high temperature
Masayoshi Akiyama, Yutaka Neishi, Yoshitaka Adachi, Kenjiro TeradaObservation by optical microscopy and EBSP have made it clear that the trigger for the grain coarsening phenomenon of austenite stainless steel BS304S31 may be the stacking faults…
Computational models for biological tissues and biomedical implants
R. Contro, P. VenaThis paper aims at showing that the finite element method is the most important numerical tool to analyse bio‐solids or bio‐fluids because of the constitutive complexity and…
Coupled material modelling and multifield structural analyses in civil engineering
Josef Eberhardsteiner, Günter Hofstetter, Günther Meschke, Peter Mackenzie‐HelnweinIn this paper, three research topics are presented referring to different aspects of multifield problems in civil engineering. The first example deals with long term behaviour of…
Molecular simulation and multiscale homogenization analysis for microinhomogeneous clay materials
Y. Ichikawa, K. Kawamura, N. Fujii, Theramast NattavutMaterials commonly involve microstructure. Clay is a microinhomogeneous material with nanoscale microstructure. Key issues to understand the behavior of such a finely…
The extended Delaunay tessellation
Nestor Calvo, Sergio R. Idelsohn, Eugenio OñateThe extended Delaunay tessellation (EDT) is presented in this paper as the unique partition of a node set into polyhedral regions defined by nodes lying on the nearby Vorono…
Pollution‐free energy production by a proper misuse of finite element analysis
Miloslav Okrouhlik, Svatopluk PtakNotes that what applied scientists in classical continuum mechanics are doing is based on knowledge established by Newton, Cauchy, Euler, Rayleigh and others, and no really…
Direct computation of instability points with inequality constraints using the FEM
H. Tschöpe, P. Wriggers, E. OñateThe subject of this paper is the computation of instability points in mechanical problems with the finite element method. The objective is to extend the application of critical…
A residual correction method based on finite calculus
Eugenio Oñate, R.L. Taylor, O.C. Zienkiewicz, J. RojekIn this paper, a residual correction method based upon an extension of the finite calculus concept is presented. The method is described and applied to the solution of a scalar…
New mixed formulations for problems in elasticity
J.K. Djoko, B.D. ReddyClassical mixed formulations of the boundary‐value problem of linear elasticity are reviewed, and a new three‐field formulation is introduced. The formulation is an extension of…
Cohesive fracture mechanics for a multi‐phase porous medium
Luciano Simoni, Stefano SecchiThis paper presents a mathematical model for the analysis of cohesive fracture propagation through a non‐homogeneous porous medium. Governing equations are stated within the frame…
New insight into optimization and variational problems in the 17th century
Erwin Stein, Karin WiechmannFirst, a synopsis of the major changes of natural science, mathematics and philosophy within the 17th century shall highlight the birth of the new age of science and technology…
Interface‐capturing finite element technique for transient two‐phase flow
Nahidh Hamid Sharif, Nils‐Erik WibergA numerical model is presented for the computation of unsteady two‐fluid interfaces in nonlinear porous media flow. The nonlinear Forchheimer equation is included in the…
The effect of the third invariant in computational plasticity
Peter Pivonka, Kaspar WillamIn this paper, we examine the influence of the third invariant in computational plasticity. For this purpose we consider the extended Leon model, an elasto‐plastic model for…
Simulation of unsteady flow and solute transport in a tidal river network
Xiaoyong ZhanA mathematical model and numerical method for water flow and solute transport in a tidal river network is presented. The tidal river network is defined as a system of open…
A computational model for generalized inelastic materials at finite strains combining elastic, viscoelastic and plastic material behaviour
D. Peric´, W. DettmerThis work is concerned with the computational modelling of non‐linear solid material behaviour in the finite strain regime. Based on the recent computational formulations for…
