The Application of Debond Length Measurements to Examine the Accuracy of Composite Interface Properties Derived From Fiber Pushout Testing
… was designed and constructed to perform fiber pushout tests at temperatures up to 800$\sp\circ$C and in a controlled environment. Preliminary pushout tests on both a pristine and a transversely fatigued SiC/Ti-6-4 composite were conducted to assess the capabilities of this apparatus. A …

Investigation of Oxide Fiber/oxide Matrix Composites With a Weak Interphase
… fiber model systems were obtained by analyzing pushout data with the linear model, the shear-lag model, and the Liang-Hutchinson model. These interface properties include interface fracture energy, coefficient of friction, clamping pressure, interface debond strength, and interface friction …

What I need from you is understanding: A critical race interview study on the withdrawal experiences of former no excuses charter school students
… of No Excuses charter schools, that of student pushout. Through the use of Critical Race Theory as a framework, this study captures the reflections of adults who experienced or witnessed pushout during their K-12 educational experience thus providing a counternarrative to majoritarian stories …

Gröbner bases in rational homotopy theory
… has no dual that characterizes the homotopy of a pushout. The main obstacle is the lack of an Eckmann-Hilton dual to the Kiinneth theorem with which to understand the homotopy of a coproduct. This difficulty disappears when working rationally, and we dualize Rector's construction of the …

Standoff screws functioning as mechanical shear connectors in composite joists
The results of sixty-five double-sided pushout tests utilizing the Elco grade 8, 5/16 in. diameter, standoff screw functioning as a mechanical shear connector are presented. In all tests, the base material, through which the screw was fastened, was fabricated out of back to back angle to simulate …

Investigations into Flange Surface Friction Effects on Shear Stud Load Transfer in Composite Bridge Girders
… primer coatings are considered in double-sided pushout experiments to quantify flange surface coating effects. Thin foil pressure gauges are used to measure stud demands while controlled normal forces are applied to each slab to allow controlled changes in flange friction force during testing. A …

Development and Application of Simplified and Advanced Modeling Procedures for Timber-Concrete Composite Structures
… phase focuses on modeling notched connections in pushout tests, while the second phase investigates their behavior in TCC beams. In each phase, detailed 2D finite element (FE) models are developed and validated against various test specimens, followed by conducting a series of parametric studies …

Strength of welded shear studs
… a lower upper limit is proposed. Eighty-seven pushout tests utilizing steel deck were also conducted. It is shown how the placement, height, and arrangement of shear studs, as well as the height and gage of steel deck affects the strength of shear connections when stiffened steel deck is used. …

Do You Hear Us? Amplifying Alternative Pathways for High School Pushouts Through Youth Participatory Action Research
… An emerging solution to address high school pushout and the STPP has been to develop Alternative Education Campuses (AECs). However, there is a current gap in the research that amplifies the counter narratives of students currently enrolled at an AEC, through their own words, using Youth …

On the Fatigue of Headed Shear Studs in Steel-Concrete Composite Bridge Girders
… high-cycle fatigue tests are conducted on stud pushout specimens at low stress ranges and combined with existing experimental data to develop probabilistic S-N fatigue capacity curves. Results from composite push-out specimens tested at stress ranges between 4.4 and 8.7 ksi suggest a fatigue …
