Effects of Shallow Bi-Angle, Thin-Ply Laminates on the Structural Performance of Composite Wings
… bring to fiber reinforced polymer composites. Coupon- and structural-level tests are conducted along with numerical simulations. According to the coupon tests, we find that shallow bi-angle fibers and thin plies can increase the axial stiffness of laminates significantly at the cost of …

Flexural Behavior of Cold-Formed and Hot-Rolled Steel Sheet Piling Subjected to Simulated Soil Pressure
… to the corresponding yield stress from tensile coupon tests to make a meaningful comparison. The results indicate that transverse stresses influence the flexural capacity of the sheet pilings. The longer span length has less amount of transverse strains, resulting in a higher moment capacity. …

A Low Cycle Fatigue Testing Framework for Evaluating the Effect of Artifacts on the Seismic Behavior of Moment Frames
… hinge regions using relatively economical coupon tests. Cyclic bend tests and monotonic tension tests on flat plate coupons that include artifacts are used to calibrate fracture parameters for different low cycle fatigue models such as the Cyclic Void Growth Model (CVGM), Stress-Weighted …

Material Properties of Human Rib Cortical Bone from Dynamic Tension Coupon Testing
… of human rib cortical bone using dynamic tension coupon testing. This study presents 117 human rib cortical bone coupon tests from six cadavers, three male and three female, ranging in age from 18 to 67 years old. The rib sections were taken from the anterior, lateral, and posterior regions on …

Experimental and numerical developments in predicting the crashworthiness of Formula One composite structures
… tools. The quasi-static and dynamic crush tests of the SIS were also complemented with similar crush tests of small flat and tubular coupons of various layups. <br/><br/>This thesis also presents some preliminary experimental studies which were performed in order to develop novel and …

Dynamic Fracture of Adhesively Bonded Composite Structures Using Cohesive Zone Models
… using the explicit code. Verification of these coupon tests leads to the crash analysis of realistic structures like the square composite tube. Analyses of bonded and unbonded square tubes are presented. These tubes shows a very uncharacteristic failure mode: the composite material disintegrates …

Analytical and Experimental Investigation of Low-Cycle Fatigue Fracture in Structural Steel
The mechanism of metal material failure due to inelastic cyclic deformations is commonly described as Low-Cycle Fatigue (LCF). Fracture in steel structures caused by earthquakes can be associated with this mechanism. Mathematical expressions describing the material deterioration due to LCF are …

AEROMECHANICS OF A DOUBLE ANHEDRAL TIP COMPOSITE ROTOR: EXPERIMENT AND MODELING
… rotating frequencies (fan plot). The hover tests were performed on the Alfred Gessow Rotorcraft Center Mach-scaled four-bladed hingeless rig. Tests were carried out up to tip Mach number of 0.6 over a collective range of $0^{\circ}$ to $10^{\circ}$. The rotor performance, blade structural …

Strength and Ductility of Concrete Cylinders Confined with Fiber Metal Laminate Composites
… phase consisted of a series of uniaxial tension coupon tests to investigate how the stacking arrangement of various E-glass fabrics and aluminum sheets could be tuned to control the yield strength, post-yield stiffness, and ductility characteristics of the FML lay-ups. Mechanical roughening of …
