Decaying states in a plate of general shape i007 in 10, the authors developed the notion of a decaying state for the particular case of the semiinfinite plate x 2 0, 1 y 1 c 1m, 1z 5 15, which was tractionfree on z h and subject to plane strain deformation independent of y. Plan the load paths in parts, structures, and assemblies. Dynamic equivalence, selfequilibrated excitation and saintvenants principle for an elastic strip. In other words, as the distance from the point of loading becomes greater, the local effects are reduced such that they can be considered not to be present.
The stresses and strains in a body at points that are sufficiently remote from points of application of load depends only on the static resultant of the loads and not on the distribution of loads. In this model, the lateral stiffness of the columns is modeled by the spring k, the damping is modeled by the shock absorber c and. The effectof gravity should therefore not be taken into account in the equation of motion of the system.

Journal of composite materials michigan state university. Mises the socalled principle of statically equivalent loads, due to saint venant, has been referred to for the last fifty years in almost all texts on elasticity. Intended primarily for teaching dynamics of structures to advanced undergraduates and graduate students in civil engineering departments, this text may also be an effective reference for researchers and practicing engineers. Disturbances travel longer distances than what we expect, because the load paths in a thin structure are much more limited. In linear elasticity, saintvenants principle is used to show that selfequilibrated loads generate local stress effects that decay away from the loaded end of a structure.
