Effect of heat treatments on the strength and stiffness of poplar

open access: yesMaderas: Ciencia y Tecnología
The influence of environmental conditions on wood material properties is known. Temperature is one of them and its effect on poplar wood has been examined in a limited way which this study tried to figure out this issue in a limited context.

Evaluation of Plasticity and Creep Parameters From Tensile Stress–Strain Data for a Range of Strain Rates

open access: yesAdvanced Engineering Materials, EarlyView.
This plot compares experimental tensile stress–strain curves (with 4 different strain rates) and corresponding modelled curves (obtained using the optimised sets of Voce and Miller–Norton parameter values shown). The inferred M‐N values, characterizing the creep, are very similar to those obtained via conventional creep testing.

COMPARISON OF HOT AND COLD MODULUS OF RUPTURE FOR SILICA BRICK [PDF]

open access: yesJournal of the American Ceramic Society, 1922
ABSTRACT Purpose of the Investigation .—(1) To obtain relative values for the cross‐breaking strength of silica brick at temperatures encountered in coke oven practice. (2) To correlate the hot modulus of rupture test, if possible, with the cold modulus of ...

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

open access: yesAdvanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Low Cycle Repetitive Loading of Ti‐6Al‐4V‐Epoxy Composite Lattice Structures for Enhanced Energy Dissipation and Damage Tolerance

open access: yesAdvanced Engineering Materials, EarlyView.
Composite Ti–6Al–4V–epoxy lattice structures are additively manufactured and epoxy infiltrated for cyclic loading. At low lattice volume fractions, hybridization produces synergistic gains in stiffness and energy dissipation. At higher volume fractions, synergy diminishes, although composites still exceed metallic lattices in specific energy ...

Some mechanical properties of plywood produced from eucalyptus, beech, and poplar veneer

open access: yesMaderas: Ciencia y Tecnología, 2014
In this study, we determined the flexural properties and tensile shear strength of five-ply plywood panels produced with eucalyptus (Eucalyptus grandis), beech (Fagus orientalis), and hybrid poplar (Populus x euramericana) using urea-formaldehyde (UF ...

MODULUS OF ELASTICITY AND MODULUS OF RUPTURE OF ELECTRICAL PORCELAIN

open access: yesJournal of the Ceramic Association, Japan, 1937
Measuring the modulus of elasticity and that of rupture for electrical porcelain with the small cross sectional area, the following results have been obtained.1. When the grain size of green body is reduced, the modules of rupture and the modulus of elasticity become larger, but the increase of the latter is smaller when compared with that of the ...

Relationships of Modulus of Rupture to Soil Properties in Konya Plain

open access: yes, 1999
Some physical and chemical analyses were done in sexteren surface (0-15 cm) soil samples from the area among Konya-Çumra-Karapmar, showing soil crusting. Relationships between sois properties and modulus of ruputre were studied.

Experimental Characterization of Mycelium‐Based Composites Under Multiple Loading Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines the mechanical response of mycelium‐based composites under compression, shear, and tension using mechanical testing and imaging methods. The comparison between unpressed and hot‐pressed specimens shows that hot pressing is associated with higher compression and shear stiffnesses.
