Finite element model of bamboo culm (Phyllostachys sp.) and its comparison to two experimental tests
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2010 The main goal of the work was to build up a general parametric finite-element model of a bamboo culm in ANSYS computational system. Subsequently the model was compared to a experimental measurements of chosen mechanical properties – three point bending ...

INVERSE MODEL OF DISPLACEMENT FOR THREE-POINT BENDING TEST
, 2021 Three-point bending is an important test for various parameters in material science. In order to validate our layered fracture model we need a relationship between the loading force and the displacement.

Three point bend creep testing of carbon/epoxy [PDF]
, 1990 This study provides data to verify theoretical models for predicting and characterizing viscoelastic behavior of fiber composites. Since performing uninterrupted creep tests for years at a time was not feasible, creep behavior was accelerated with elevated temperatures.

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity
Molecular Oncology, EarlyView.Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Three-Point Bending Fatigue Test of TiAl6V4 Titanium Alloy at Room Temperature
Advances in Materials Science and Engineering, 2019 A polycrystalline alpha-beta TiAl6V4 alloy in the annealed condition was used for the three-point bending fatigue test at frequency f∼100 Hz. The static preload Fstat. = −15 kN and variable dynamic force Fdyn. = −7 kN to −13.5 kN were set as fatigue test
