These models provide a powerful, yet adaptable way of representing many aspects of the dynamic stress-strain behavior of geological materials. They have been extensively used for more than three decades to characterize soils and rocks as well as concrete. The modern series of CAP models, introduced in the early 1970’s as a result of government-sponsored university and corporate R&D technology, is based on the adaptation of several earlier models. The basic behavior of the early models is briefly discussed and compared, and the reasons for the introduction of CAP models are outlined. Many adaptations of the CAP model have been developed since the first model was introduced, and the salient features of some of these model extensions are also reviewed. 000004656 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000004656 653__ $$aCap Model, plasticity, geological materials 000004656 7112_ $$a15th ASCE Engineering Mechanics Division Conference$$cNew York (US)$$d2002-06-02 / 2002-06-05$$gEM2002 000004656 720__ $$aSandler, Ivan S. 000004656 8560_ $$ffischerc@itam.cas.cz 000004656 8564_ $$s59930$$uhttp://invenio.itam.cas.cz/record/4656/files/122.pdf$$yOriginal version of the author's contribution as presented on CD, . 000004656 962__ $$r4594 000004656 980__ $$aPAPER
