TL;DR: In this article, the results of an overall experimental characterization of the mechanical behavior of a Low Density Sheet Molding Compound (LD-SMC) are presented, which is a polyester matrix containing mineral charge (CaCO3) reinforced by discontinuous bundles of glass fibers and Hollow Glass Microspheres (HGM).
Abstract: This paper presents the results of an overall experimental characterization of the mechanical behavior of a Low Density Sheet Molding Compound (LD-SMC). LD-SMC is a polyester matrix containing mineral charge (CaCO3) reinforced by discontinuous bundles of glass fibers and Hollow Glass Microspheres (HGM). After a description of its specific microstructure using several experimental methods (notably a new ultrasonic method), the overall mechanical response of two microstructure configurations (Randomly Oriented (RO) and Highly oriented (HO)) is analyzed at both macroscopic and microscopic scales in the case of tensile and compression tests. HGMs are homogeneously distributed into the overall volume of the material. At the microscopic scale, in-situ tensile tests inside a SEM and fracture surfaces observations allows analyzing the specific damage mechanisms occurring during tensile and compression loading performed in the mold flow direction (HO-0°) and perpendicularly to it (HO-90°). A strong coupled influence of the presence of the HGM and fibers orientation has been emphasized. The results show that for HO-0° configuration fiber-matrix debonding appears to be the predominant damage mechanism, whereas for HO-90° configuration HGM-matrix debonding appears to be the predominant damage mechanism. High speed tensile tests are achieved using servo-hydraulic test equipment in order to study the strain rate effects (until 80 s−1) on mechanical macroscopic responses of HO-0°, RO and HO-90° samples. Strain rate has an obvious influence on the inelastic properties of LD-SMCs samples for all microstructures particularly on the damage threshold.

TL;DR: Although numerous works have been already done on the PQIP, the development of multi-objective optimisation frameworks considering real production constraints under parameters uncertainty is necessary and by the Industry 4.0 trend, the creation of integrated models aiming to plan the inspection, maintenance and production activities simultaneously, seems to be an important potential future research direction.

TL;DR: In this paper, the optimal choice of building energy efficiency (BEE) standard in the context of centralised urban district heating system in northern China was investigated by employing a techno-economic analysis approach, demonstrating that the current BEE standard implemented in the Chinese cities should be tightened further in order to achieve a socially optimal level.

TL;DR: The first results achieved in the French ANR project BANET (Body Area NEtwork and Technologies) concerning the channel characterization and modeling aspects of Body Area Networks (BANs) are presented.
Abstract: The first results achieved in the French ANR (National Research Agency) project BANET (Body Area NEtwork and Technologies) concerning the channel characterization and modeling aspects of Body Area Networks (BANs) are presented (part II). A scenario-based approach is used to determine the BAN statistical behavior, trends, and eventually models, from numerous measurement campaigns. Measurement setups are carefully described in the UWB context. The numerous sources of variability of the channel are addressed. A particular focus is put on the time-variant channel, showing notably that it is the main cause of the slow fading variance. Issues related to the data processing and the measurement uncertainties are also described.
