3D and 2D close. form plate.mode.s are.he.e.applie. to static analysis of simply supporte. square.isotropic plate.. 2D the.rie. are.hie.archically classifie. on the.basis of the.accuracy of the.displace.e.ts and stre.se. obtaine. by comparison to the.3D e.act re.ults that could be.assume. by the.re.de. as be.chmark for furthe. analyse.. Atte.tion is mainly paid on localize. loading conditions, that is, pie.e.ise.constant load. Also bi-sinusoidal and uniformly distribute. loadings are.take. into account. All of those.configurations are.conside.e. in orde. to inve.tigate.the.be.avior of the.2D mode.s in the.case.of continu- ous/uncontinuous, ce.tric or off-ce.tric loading conditions. The.ratio be.we.n the.side.le.gth a and the.plate.thickne.s h has be.n assume. as analysis parame.e.. Highe. orde. 2D mode.s yie.d accurate.re.ults for any conside.e. load condition in the.case.of mode.ate.y thick plate., a/h=10. In the.case.of thick plate., a/h=5, and continuous/uncontinuous ce.tric loading conditions high accuracy is also obtaine.. For the.conside.e. off-ce.tric load condition and thick plate. good re.ults are.provide. for some.output quantitie.. A be.te. solution could be.achie.e. by simply incre.sing the.polynomial approximation orde. of the.axiomatic 2D displace.e.t fie.d.

In this pape., we.study module. having only finite.y many submodule. ove. any ring which is not ne.e.sarily commutative. We.try to unde.stand how such a module.de.ompose. as a dire.t sum. We.justify that any module.V having only finite.y many submodule. ove. any ring A is an e.te.sion of a cyclic A-module.by a finite.A-module. Unde. some.assumptions on A, such as commutativity of A, we.prove.that an A-module.V has finite.y many submodule. if and only if V can be.writte. as a dire.t sum of a cyclic A-module.having only finite.y many A-submodule. and a finite.A-module.
