EVALUATION OF DEFORMATION CHARACTERISTICS OF SOIL BY BENDER ELEMENT TEST

Doboku Gakkai Ronbunshu, 2003
ベンダーエレメント試験 (以下BE試験) の受信波によって, 土の減衰振動ならびに共振を観察することができるという仮定に基づき, 共振法土質試験の理論を援用して2通りの方法でせん断弾性係数および減衰比を求める手法を示している. 粘土, 泥炭試料についての実験結果からこれらの方法によって求めたせん断弾性係数の値は, せん断波の到達時刻を受信波のピーク点で定義した場合よりは (試料によって3～7倍) 大きな値となること, また, 減衰比についてはBE試験による既往の報告例はないが, 繰返し三軸試験によって従来報告されている値と近いことを示している. これらの結果をふまえ, 従来の方法に加えて本研究で提案する2通りの方法を併用することにより, BE試験の活用範囲がさらに広がることを示唆している.

Incorporation of Selenium into Sol–Gel‐Derived Bioactive Glass: Influence on Glass Structure, Bioactivity, and its Selective Cytotoxicity

Advanced Engineering Materials, EarlyView.
Selenium was incorporated into a sol–gel‐derived bioactive glass to enable sustained therapeutic ion release. The selenium‐containing glass preserved bioactivity while selectively inducing cytotoxicity in osteosarcoma cells and maintaining osteoblastic viability.

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Bender element sensor technology to quantify local stiffness enhancement of geogrid-stabilized aggregate specimens [PDF]

E3S Web of Conferences
Geogrids improve pavement performance and extend lifespan by making the unbound aggregate base/subbase course stiffer. Extruded (i.e., punched and drawn) geogrids are widely used in pavement applications. This paper presents an experimental evaluation of

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Laboratory Investigation on Shear Modulus and Damping Properties of Port Soft Clay Improved by Dynamic Compaction

Applied Sciences
Dynamic compaction has been widely applied to reinforce soft soils in port areas due to its high efficiency and cost-effectiveness. However, a comprehensive understanding of the deformation mechanisms and stiffness evolution of treated soils under static

Geogrid-stabilized eco-friendly aggregates for pavement base – quantitative assessment using Bender Element sensor technology [PDF]

E3S Web of Conferences
Geogrids provide mechanical stabilization by effectively restraining aggregate movements in a granular layer which in turn improve pavement performance and extend its lifespan.
