Three-point bending of electrospun TiO2 nanofibers
Materials Science and Engineering: A, 2005 TiO2 (anatase) and TiO2/PVP nanocomposite nanofibers with average diameters of 53 and 109 nm, respectively, were synthesized via sol-gel chemistry in combination with an electrospinning process. This produced continuous nanotibers that were characterized

The nonlinear bending-torsion theory for curved rods as Gamma-limit of three-dimensional elasticity [PDF]
, 2006 The problem of the rigorous derivation of one-dimensional models for nonlinearly elastic curved beams is studied in a variational setting. Considering different scalings of the three-dimensional energy and passing to the limit as the diameter of the beam

Application of Mean Modulus in Three-Point Bending and Roll Forming. [PDF]
Materials (Basel), 2023 Nonlinear unloading plays an important role in predicting springback during plastic forming process. To improve the accuracy of springback prediction which could provide a guide for precision forming, uniaxial tensile tests and uniaxial loading–unloading–loading tensile tests on SUS304 stainless steel were carried out.

Crackling noise in three-point bending of heterogeneous materials [PDF]
Physical Review E, 2011 We study the crackling noise emerging during single crack propagation in a specimen under three-point bending conditions. Computer simulations are carried out in the framework of a discrete element model where the specimen is discretized in terms of convex polygons and cohesive elements are represented by beams.

Permanent indentation characterization for low-velocity impact modelling using three-point bending test [PDF]
, 2014 This paper deals with the origin of permanent indentation in composite laminates subjected to low-velocity impact. The three-point bending test is used to exhibit a non-closure of matrix crack which is assumed as a cause of permanent indentation ...

A review and application of the failure criteria on a graphite epoxy under three-point bending test [PDF]
MATEC Web of Conferences, 2019 The application of failure criteria are difficult partly because they are too various and must be validated by biaxial tests, which are expensive to be achieved.
