Abstract The dynamic fracture properties of porous ceramics were studied using single bunch synchrotron X-ray phase contrast imaging. modified brazilian geometry was used to initiate and propagate a pure mode I crack. specimen compressed the Split Hopkinson bars at strain rates order $$10^2$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msup> <mml:mn>10</mml:mn> <mml:mn>2</mml:mn> </mml:msup> </mml:math> s $$^{-1}$$ <mml:mmultiscripts> <mml:mrow/> <mml:mrow>...
Abstract A strategy of CO 2 ‐assisted extrusion foaming PMMA‐based materials was established to minimize both foam density and porosities dimension. First a highly ‐philic block copolymer (MAM: PMMA‐PBA‐PMMA) added in PMMA order improve saturation before foaming. Then the extruding conditions were optimized maximize uptake prevent coalescence. The temperature reduction led an increase pressure barrel, favorable cell size reduction. With combination material formulation strategy, very...
The demand for bio-sourced materials is currently increasing. Cork material because of its unique properties (fire resistant, energy absorbing, …) then an excellent candidate a large set applications. In order to widen possible uses, cork agglomerates with reinforcements at 0.48 density were studied compare their mechanical performances classical agglomerates. This paper investigates the effect these foreign on agglomerated under compressive loading. behavior has been determined as function...
Polymeric cellular materials are used in many different application domains such as transport, sport, food, health and energy. Therefore, the conditions of use these represent wide temperature strain-rate ranges. The mechanical behaviour foams demonstrate a strong dependency to it. In order be able predict dependency, its origin has better understood. For this study, bio-based material, agglomerated cork, been chosen evaluate behaviour. visco-elastic material was first studied between −80°C...
ABSTRACT This research delves into the fracture analysis of cellular thermosetting polymers using Mode I tests with a compact tension geometry subjected to both monotonic and cyclic loadings. The equivalent linear elastic mechanics concept effectively described crack initiation propagation. Numerical simulations estimated length aligning experimental measurements. Resistance curves revealed transient regime followed by self‐similar relatively constant energy, typical quasi‐brittle materials....
This study presents the mechanical response of hazelnut shells under compressive loadings with regards their hierarchical structure. The hazelnuts were loaded in quasi-static compression and both influence loading direction, moisture content shell evaluated. Moreover, fracture mechanisms nutshell studied thanks to post-mortem SEM observations.The macroscopic is characterized by a linear elastic followed brutal at maximum force. It typical an elastic-brittle behavior. Modifying direction or...
This study focuses on the strain rate effect mechanical behavior under compression loading of a thick cellular structural adhesive (TCSA). The material is used as reinforcement and can have different expansion thicknesses in service depending gap to fill between parts. Two (5 7 mm) therefore two densities are then studied. Compressive tests were conducted at room temperature (24◦C) with universal testing frame ZwickRoell Z250 for low rates from 5 · 10−3 0.7 s−1 higher up 2000 using split...
