Bio-based phase change material for enhanced building energy efficiency: A study of beech and thermally modified beech wood for wall structures
(John Wiley & Sons, Inc., 2024)This study investigated the impregnation of beech and thermally modified beech (TMB) with a ternary mixture of capric acid, palmitic acid, and stearic acid as a bio-based phase change material (BPCM). Finite element method ... -
Effects of Wood Particles from Deadwood on the Properties and Formaldehyde Emission of Particleboards
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2022)The volume of deadwood increases annually because of changes in environmental, climatic, and hydrological conditions. On the other hand, during the last decade, manufacturers of wood-based boards have been facing an acute ... -
Elasto-plastic material model of oak at two moisture content levels
(Walter de Gruyter GmbH, 2022)The mechanical properties of wood show a very high dependence on the moisture content (MC). A consideration of MC in numerical simulations increases the applicability of such prediction with respect to application and ... -
Fomes fomentarius and F. inzengae-A Comparison of Their Decay Patterns on Beech Wood
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2023)Wood-decaying fungi are responsible for the degradation of wood and the alteration in its material properties. Fomes fomentarius (L.) Fr. is one of the most common white-rot fungi colonising coarse wood and standing trees. ... -

(2021)Publikace se věnuje metodickému popisu tradičního (ručního) opracování dřeva pro konstrukční opatření při opravách historických staveb. V metodice jsou prezentovány výsledky experimentálních testů při těžbě dřeva v různých ... -
Physical-Mechanical Properties of Peat Moss (Sphagnum) Insulation Panels with Bio-Based Adhesives
(MDPI AG (Multidisciplinary Digital Publishing Institute-MDPI), 2022)Rising energy and raw material prices, dwindling resources, increased recycling, and the need for sustainable management have led to growth in the smart materials sector. In recent years, the importance and diversity of ... -
The role of geometry precision in frequency-resonance method for non-destructive wood assessment - numerical case study on sugar maple
(CRC Press/Taylor and Francis Group, 2023)The application of frequency-resonance method (FRM) for precise log bending testing is limited by complex geometry; usually the cone with variable cross. This case study presents the relationship among non-destructively ... -
Using 3D digital image correlation in an identification of defects of trees subjected to bending
(Elsevier GmbH, 2019)Abrupt changes of climate have intensified during the last few decades, bringing higher risks from tree failures by either uprooting or stem breakage. To eliminate the risks, many techniques of tree assessment are being ...
