Bending Test Study Elastic Bending of a Beam Formulation: bending a cantilevered

beam Maximum load for elastic deformation Conduct Bending Test Determine Elastic Modulus & Poisson’s

Ratio of material Comparison to handbook value and

previous Lab #1 results

Pure BendingMaterial Assumptions Homogeneous Isotropic

Geometry/Load Assumptions

X-section has a plane of symmetry

Bending moment applied in that plane

Deformation Grids

Neutral Axis and Strain(elastic and plastic range)

Elastic Strain & Stress Distribution

Estimating Maximum Load

Poisson’s Effect

Bending Test Data Sheet

Conduct the Bending Test

Please initialize the Strain Meter a couple of times to ensure that it indicates zero strains at zero load, and that there is NO DRIFT with time
