Sun School of Aeronautics and Astronautics Purdue University W. Lafayette, Indiana U. Prepared with the assistance of Mr. com IP: Mechanics of Aircraft structures C. Sun 1. If the total wall contour length see Fig. Note that for closed thin-walled sections such as the one in Fig. The moment of inertia I of the cross-section can be calculated by considering the four segments of thin walls and using the formula for a rectangular section with height h and width w.
Note that the Parallel Axis Theorem is applied. Sun 3 Two approaches are employed to find the solution. i Assume that the bending stress reaches the allowable allowableσ first and find the corresponding bending maximum bending moment.
Consequently, the optimal ratio obtained is not valid and different assumption needs to be made. ii Assume now that failure is controlled by shear stress. Figure 1. Sun 4 From the above two approaches, we have the conclusions. Assume that t and h are to be fixed for an aluminum T6 I-beam. Find the width b for the aluminum beam so that its bending stiffness EI is equal to that of the steel beam.
Compare the weights-per-unit length of these two beams. Which is more efficient weightwise? It means that the ALUMINUM BEAM IS MORE EFFICIENT! Compare its weight with that of the aluminum mechanics of aircraft structures 2nd edition pdf download. If w is regarded as a positive displacement or deflection in the positive y-direction, find the positive direction of the bending moment.
State the reason. It is quite obvious that both E and I are always positive. It is not difficult to observe that the slope dx dw increases with increasing x and thus a positive 2 2 dx wd. Use bending rigidity as the criterion for comparison. lE rE 2 Moment of inertia I : i Left cross-section: There is another condition, two cross-section have the same area, which will help to solve b. i If lr E ii If lr E iii If lr E Sun 2.
b Calculate the six strain components. Solution: a Sincemechanics of aircraft structures 2nd edition pdf download, there is no deformation in the z-direction and the deformation can be represented in the x-y plane.
Sun b Strain components are: nents,Normal strain compo This displacement field does not yield any strains; it only produces a rigid body rotation. What is the change of distance between mechanics of aircraft structures 2nd edition pdf download two points after deformation? Calculate the strain components corresponding to the given displacement field.
Use the definition of xxε to estimate the change of distance between the two points. Compare the two results. Sun From the deformed shape, find the normal strain for material along the line CB by comparing the deformed length ''BC and undeformed length CB.
Compare Solution: a The result of example 2. From which we obtain Note that 2, mechanics of aircraft structures 2nd edition pdf download. Assume a state of plane stress parallel to the x-z plane, i. Sun c Applying the B. Find the normal component nσ of the stress vector.
Hint: From the equilibrium equation Figure 2. Solution: a The stress given in problem 2. So here we can use the 2D analysis on the x-y plane just for other principal values. The stress vector acting on this surface, from equation 2.
This leads to the conclusion that the stress vector is always perpendicular to mechanics of aircraft structures 2nd edition pdf download surface. Find the corresponding strain components. The bulk modulus K of an isotropic solid is defined as the ratio of the average stress and the volume change, i. The containing walls are rigid and smooth frictionless.
Find the values of k for plane strain and plane stress conditions, respectively, in the stress-strain relation obtained from the compression test above. If the lateral surface of the bar is confined and not allowed to contract during loading, find the force that is needed to produce a 1 percent longitudinal strain. Compare this with the corresponding load for the bar under simple tension. a Aluminum alloys are usually considered isotropic, so the above three-dimensional stress-strain relations can be utilized.
Also, we need to produce a 1 percent longitudinal 2. Sun strain, which means
