In this study, we investigate the cracking behaviour of softwood species using MMCG fracture test. Our primary objective is to directly measure crack length propagation in mode I loading and associated parameters. To achieve this, employ Arcan system apply load specimen. We used Digital Image Correlation (DIC) displacement strain fields ahead advancing crack. Fracture properties were determined compliance method, providing an estimate critical energy release rate for I. Two different...
The rubber tree (Hevea brasiliensis) is the main source of natural production, with more than 14 million tonnes produced each year. Unfortunately, throughout their economic lifespan on plantation (between 35 and 40 years), heveas trees are sensitive to wind damage, especially trunk breakage. Over a 30-year period, it estimated that losses due breakage stems reach nearly 40%. Industrial hevea plantations organized in monoclonal plots. Clones selected based productivity, disease resistance,...
The crack characterization in a pre-cracked aluminum specimen is investigated this study using the grid method. images of are analyzed to provide tip location as well displacement and strain fields on surface during tensile test. Experimental data used calculate energy release rate with compliance method A fracture analysis also performed invariant M $$\uptheta $$ integral which both real virtual introduced. This implemented finite element software Cast3M. Both approaches give similar...
Chloride-induced corrosion and load induced concrete cracking affect the serviceability safety of reinforced (RC) structures. Once these phenomena occur simultaneously, prediction RC structures’ lifetimes becomes a major challenge. The objective this paper is to propose methodology evaluate effect loading on mechanism chloride ion penetration in concrete. proposed will be based Bayesian networks. networks are useful update lifetime assessment experimental data as well characterize...
The mechanical behavior of Aucoumea Klaineana Pierre (AKP) under progressive static and cyclic compressive loading at various moisture content (MC) stages is investigated herein. This tropical species, also called Okume, originates from the Congo Basin, particularly Gabon. experimental device used composed an electronic testing machine, a system yielding corresponding MC, AKP wood samples. In all, 15 samples were loaded in statics, different MC levels, until first cracks led to...
This work is devoted to 3-point bending tests performed on tropical specimens of Moabi (Baillonella toxisperma) from Gabon. The beams are formerly subjected long-term loading in three media (air-conditioned, unsheltered and sheltered outdoor) a environment. were sawn into nine 340 mm long sections subdivided the vertical direction (top section, middle section bottom section). From each two extracted for test, tensile test four compression test. In present study, 81 with cross-section 15 x...
