Mechano-sorptive

WebMechano-sorptive creep was independently reported in the literature for wool [1,2] and wood [3,4] in the late 1950s and early 1960s. Ten years later it was also found in paper [5,6]. In the 1990s mechano-sorptive creep was also observed in some synthetic fibres, for example WebNov 25, 2024 · Creep deflection accelerates with a moisture content change, which is known as mechano-sorptive creep. Therefore, the result of this study is limited in constant environmental conditions, and additional creep tests might be required under variable environmental conditions. Fig. 6

Long-term deflection … WebThe results showed that the mechano-sorptive strain during desorption of moisture was proportional to applied stress and reached the maximum value in the tangential direction. Also, the mechano-sorption coefficient depended on wood orientation and reached the maximum value of 5.46 × 10-2 in the tangential direction. lithium tox symptoms https://robertgwatkins.com

WebThe creep model currently accounts for the creep of CLT under a constant load, which is a preliminary step towards predicting the post-tension loss of PT shear walls. In future work, the data recorded from the tests should be analyzed to update the creep model to include mechano-sorptive effects and a varying load due to PT loss. WebThe measured mechano-sorptive deformation in compression was significantly greater than that measured in tension (4 times higher at cumulative MC 60% than in tension). However, the developed compression protocol was less accurate, with a tendency to overestimate the magnitude of subsequent experimental creep behavior. A multi-physics model of ...
