New methodology for calculating damage variables evolution in Plastic Damage Model for RC structures [PDF]
, 2017 The behavior of reinforced concrete (RC) structures under severe demands, as strong ground motions, is highly complex; this is mainly due to joint operation of concrete and steel, with several coupled failure modes.

New Variable Compliance Method for Estimating In-Situ Stress and Leak-Off from DFIT Data
, 2017 It is shown that using Carter leak-off is an oversimplification that leads to significant errors in the interpretation of DFIT data. Most importantly, this article reveals that previous methods of estimating minimum in-situ stress often lead to ...

Variable Stiffness Structures Utilizing Pneumatic Artificial Muscles
MATEC Web of Conferences, 2019 Pneumatic artificial muscles (PAMs) can offer excellent force-to-weight ratios and act as shape-changing actuator under injecting the actuation fluid into their bladders. PAMs could be easily utilized for morphing structures due to their millimeter-scale

Variable Stiffness Prosthetic Foot
, 2022 Prosthetic devices are intended to replace missing limbs. Although this statement is simple, the design, testing, and validation of these devices are considerably complex. A number of energy-storing-and-returning prosthetic feet are commercially available, and the recently developed bionic prosthesis aims to increase ankle push-off power or ankle joint

Advanced Engineering Materials, EarlyView.Four‐point bending tests are conducted in an argon atmosphere on commercial MgO‐C brick grades with and without MgO‐C recyclate from room temperature up to 1300 °C. No detrimental effect of the MgO‐C recyclates on bending strength is found. Instead, a decisive influence of the total carbon content is observed, with lower total carbon contents ...
