For An Aluminum Sheet Under Plane Stress Loading

The follow web pages contain engineering design calculators that will determine the amount of deflection and stress a flat plate of known thickness will deflect under the specified load and distribution.

For an aluminum sheet under plane stress loading.

Now y 0 so y et 2 51 mpa 1 10 for an aluminum sheet under plane stress loading x 0 003 and y 0 001. Engineering calculators menu engineering analysis menu. 1 plane stress analysis which includes problems such. Ey 1 e σy νσy ex 1 e σx νεey ν σx.

Now σy 0 so σy 51 mpa 2ρ1 10 for an aluminum sheet under plane stress loading εx 0 003 and εy 0 001 assuming that e is 68 gpa and ν 0 30 find εz. Flat plate deflection calculator flat plate stress calculator the plate deflects. Many of the stress and deflection equations and calculators referenced from. 1 plane stress analysis which includes problems such as plates with holes fillets or other changes in geometry that are loaded in their plane resulting in local stress concentrations.

At other points there are biaxial stresses in the plane of the plate. The middle surface halfway between top and bottom surfaces remains unstressed. Ey 1 e y y ex 1 e x ey x. Plane stress and plane strain equations the two dimensional element is extremely important for.

Hence it is only recently that a need has arisen to establish if the plane stress fracture toughness of aluminum increases with increasing loading rate. The pin is to be made from a stronger material. Elastic plastic behavior of two types of steel sheets for press forming an aluminum killed mild steel and a dual phase high strength steel of 590 mpa ultimate tensile strength under in plane cyclic tension compression at large strain up to 25 strain for mild steel and 13 for high strength steel have been investigated. Assuming that e is 68 gpa and 0 30 find z.

The axes are usually chosen such that the x y plane is the plane in which the stresses act fig. If the stress state at a material particle is such that the only non zero stress components act in one plane only the particle is said to be in plane stress. Flat plates stress deflection equations and calculators. We will use this form for design bearing stress for aluminum in this book.

As shown in figure 3 17. Non zero stress components acting in the x y plane. Elastoplastic investigations of aerospace aluminum are important in the development of an understanding of the possible cyclic transient effects and their contribution to the material performance under cyclic loading. 3 26 a rectangular bar is used as a hanger.
