Elastic Stability,ns of one-dimensional problems without constraints, where the functional F depends on z and z′ only. So we are sure that we can find out the conjugate points by looking for neighbouring solutions only in those cases where these conditions are satisfied.

FATAL

Describing Quantities of Continua,he next sub-section. We will use the normal tensor notation for the description of COSSERAT- continua, whereas Professor LIPPMANN used unit base vectors. The difference will be pointed out at the end of sect. 4. 2.

forager

Elastic Stability,nishes in any case if at least two neighbouring solutions intersect each other at the endpoints of the considered interval. But it is unknown for most of the problems whether such neighbouring solutions must always exist at conjugate points. This is, in the lecture, proved only for LAGRANGE-variatio

Canonical Equations, find out the equations of motion in a simpler way than, for example by using LAGRANGE-equations of 2nd kind. But the main reason for establishing the canonical equations is the fact that they lead to JACOBI’s integration theory which does not belong to our material
