Characterization of Nb₃Sn superconducting strand under pure bending
… which includes uniaxial tension or compression, bending, and transverse compression. A bending mechanism was designed and used to characterize the bending strain behavior of two different types of Nb₃Sn superconducting strand at 4.2K in a magnetic field. Results showed that the critical current …

Estudo da flexão em vigas de alvenaria armada de tijolo vazado de barro
Studying the pure bending in reinforced masonry beams made with hollow clay bricks. With this aim fifteen beams with approximately the same geometrical characteristics and the same transversal reinforcement were tested until the failure. The variable parameters were the type of brick, the …

Stress distribution around holes in laminated composite plates
… around holes in laminated composite plates under pure bending. The shear deformation, lamination theory is derived and employed for the analysis of circular, elliptical, square, and diamond-shaped holes piercing the laminated composite plate. Each layer of the laminate is assumed to be homogeneous …

Optimization of thin-wall cylindrical shells with compliant cellular-solid cores
… to a prescribed load in uniaxial compression or pure bending. The analysis gives the values of the shell thickness, the core thickness, and the core density that minimize the weight of the structure for both loading scenarios.

Stress concentration factors of stepped structures and shouldered shafts under combined loading
… For the two- dimensional case, axial and bending loads were applied separately and then superpositioned to evaluate the effect combined loading has on stepped structures. The finite element analysis results from the combined loading agrees to within four percent of the results obtained by …

Piezoelectric response of bone and tendon subjected to inhomogeneous stress
… to in-homogeneous stress, as in cantilever bending, they do not obey the classical piezoelectric theory, although the piezoelectric minerals quartz and tourmaline do. This thesis shows that an adequate, extended theory of piezoelectricity can be developed by including in addition to the …

A Finite Element Study of Stresses in Stepped Splined Shafts, and Partially Splined Shafts Under Bending, Torsion, and Combined Loadings
… the spline teeth are modeled in three radii (R). Bending, torsion, and combined loads are applied to each model, including several combinations of bending and torsion between pure bending and pure torsion. Finite element stress results are converged to within 2% for verification. The stresses in …

Modeling of sheet metal fracture for shell finite elements with component level validation
… non-proportional and combined membrane and bending loading. The DSSE-HC model for shell elements covers three types of ductile failure observed in sheet metals: (1) in-plane shear localization, (2) biaxial fracture not preceded by localized necking, aka surface cracking, and (3) biaxial …

Prediction of service load of concrete structures after cracking using ultrasonic technique
… for design purpose. By combining the effects of pure bending and an applied axial force on a cracked flexural member, a new fracture model was proposed to predict crack propagations in RC beams. The model assumes elastic-plastic behavior of the reinforcement and a constant fracture angle of the …
