During the last 50 years, the equipment of investigating dynamic homes have ended in major advances. This ebook explores dynamic checking out, the tools used, and the experiments played, putting a selected emphasis at the context of bounded medium elastodynamics. Dynamic exams have confirmed to be as effective as static exams and are usually more uncomplicated to take advantage of at reduce frequency.

10b). It is usual in such instances to let A+ B = -Pa2/2GI. This does not increase the constants of integration, which decide the boundary conditions because if A is known, B can be found. Separating the variables· for X -Px2 dfz(x) A=--+--2EI dx giving Px 3 f 2 (x) = 6EI + Ax + F and for y ~ - vPy2 dfl (y) B + 2GI - 2E I + ~ giving _ ~ vPy 3 fl (y) - 6GI - 6EI + By + H F and H both constants of integration to be determined from the boundary conditions. lOd) (2.

The boundary conditions are: Radial stresses are zero at the inside and outside surfaces a r = 0 for r = a and r = b (a) There can be no resultant force over the end of the bar (b) By taking moments about the axis 0 (c) From (a) -+ A a2 2Cr + B(l + A b2 2C + B(l + -+ (b) gives Ja 6dr = 1 _cp(dr) d2 dr2 0 2~na) 0 2~nb) r = ~d~ dr b and this is already satisfied by (a).

P = Hence xJfl(y)dy Now the constants L, M and N have to be determined. There can be no resultant force over the end of the plate so for unit thickness or Ja(Lxy + Mx)dy + Nxy 0 -a 2Max 0 giving M and q, =0 = ~xy3 6 (2. ) Thus that is - L 3P 2a 3 and the complete stress function is cp = _ 3P 2a 3 xy 3 + 3P 4a xy If I is the second moment of area for the cross-sectio n I Hence 2a 3; 3 L and a a (2. 9a) X y 0 (2. 9 can be found. Note that ox = -(Px)y/I = -My/I where M is the bending moment at a section x, and when y is negative·, stresses are tensile as expected.
