TL;DR: In this article, the authors report on numerical investigation on the behavior of a polymer electrolyte membrane fuel cell during a non-optimized start-up procedure from (−20°C) with a two-dimensional model that couple transport, electrochemical reaction, ice formation and accumulation and mechanical stress induced by ice.

TL;DR: In this article, a three field variational framework is used to formulate a new class of mixed finite elements for the elastoplastic analysis of 2D problems, which are based on the independent interpolation of the stress, displacement and plastic multiplier fields.

TL;DR: In this article, the authors present the possibility of combining the use of tests on bulk specimens and tests on bonded assemblies, with a pressure vessel especially designed to study the influence of hydrostatic stress.
Abstract: The modelling of the non-linear behaviour of ductile adhesives requires a large experimental database in order to represent accurately the strains which are strongly dependent on the tensile-shear loading combination. Various pressure-dependent constitutive models can be found in the literature, but only a few experimental results are available, for instance, to represent accurately the initial yield surface taking into account the two stress invariants, hydrostatic stress, and von Mises equivalent stress. This paper presents the possibility of combining the use of tests on bulk specimens and tests on bonded assemblies, which strongly limit the influence of the edge effects, with a pressure vessel especially designed to study the influence of hydrostatic stress. The latter allows pressures up to 100 MPa to be applied during mechanical testing. For a given strain rate of the adhesive, experimental results using various stress paths are presented in order to analyse the influence of the hydrostatic stress on the mechanical behaviour of an adhesive. The analysis of the results focuses herein on the modelling of the initial yield surface, but such results are also useful for the development of the flow rules in the case of 3D pressure-dependent models.

TL;DR: In this article, the performance of a precast concrete sandwich panel is investigated using high-definition finite element (FE) models, based on 3D brick and 2D interface elements, to assess the capacity of this technology under shear, tension and compression.
Abstract: The focus of the present study is to investigate both local and global behaviour of a precast concrete sandwich panel. The selected prototype consists of two reinforced concrete layers coupled by a system of cold-drawn steel profiles and one intermediate layer of insulating material. High-definition nonlinear finite element (FE) models,based on 3D brick and 2D interface elements, are used to assess the capacity of this technology under shear, tension and compression. Geometrical nonlinearities are accounted via large displacement-large strain formulation, whilst material nonlinearities are included, in the series of simulations, by means of Von Mises yielding criterion for steel elements and a classical total strain crack model for concrete; a bond-slip constitutive law is additionally adopted to reproduce steel profile-concrete layer interaction. First, constitutive models are calibrated on the basis of preliminary pull and pull-out tests for steel and concrete, respectively. Geometrically and materially nonlinear FE simulations are performed, in compliance with experimental tests, to validate the proposed modeling approach and characterize shear,compressive and tensile response of this system, in terms of global capacity curves and local stress/strain distributions. Based on these experimental and numerical data, the structural performance is then quantified under various loading conditions, aimed to reproduce the behaviour of this solution during production, transport, construction and service conditions.
