Endrullis, Jörg (author), Hansen, H.H. (author), Hendriks, Dimitri (author), Polonsky, Andrew (author), Silva, Alexandra (author)We present a coinductive framework for defining and reasoning about the infinitary analogues of equational logic and term rewriting in a uniform way. We define Equation found, the infinitary extension of a given equational theory =R, and →<sup>∞</sup>, the standard notion of infinitary rewriting associated to a reduction relation →R, as...journal article 2018

Rajabzadeh, Aydin (author), Hendriks, R.C. (author), Heusdens, R. (author), Groves, R.M. (author)In this paper, we used the efficient formulation of the approximated transfer matrix model (ATMM) for the analysis of fibre Bragg grating (FBG) sensors' response under anti-symmetrical strain fields. Exploiting the flexible representation of the transfer matrices in this new model, we will analytically prove that any sort of anti-symmetrical...conference paper 2018

Pari, M. (author), Rots, J.G. (author), Hendriks, M.A.N. (author)This article presents a new non-proportional loading strategy for Sequentially Linear Analysis (SLA), which is a robust secant stiffness based procedure for nonlinear finite element analysis of quasi-brittle materials, like concrete and masonry.

Esposito, R. (author), Hendriks, M.A.N. (author)The assessment of concrete structures affected by alkali–silica reaction (ASR) is a complex problem due to the multiscale nature of this long-term phenomenon. The reaction starts within the concrete constituents and developed at aggregate level by inducing swelling and deterioration of concrete material, which eventually affect the capacity of...journal article 2017

Non-linear finite element analyses applicable for the design of large reinforced concrete structuresEngen, M (author), Hendriks, M.A.N. (author), Øverli, Jan Arve (author), Åldstedt, Erik (author)In order to make non-linear finite element analyses applicable during assessments of the ultimate load capacity or the structural reliability of large reinforced concrete structures, there is need for an efficient solution strategy with a low modelling uncertainty. A solution strategy comprises choices regarding force equilibrium, kinematic...journal article 2017
