Opis:: A review of various bulk metal forming processes that take into account influence of strain path changes on material flow is presented in this paper. Particular attention is put on computer aided design of innovative angular accumulative drawing (AAD) operation. Research in the area of development of metal forming processes taken advantage of strain path phenomena is conducted in many scientific laboratories as the strain patch change effect influences many crucial properties of the deformed material. As a result it provides a possibility of forming materials, which are e.g. difficult to form in a conventional manner. Advantages and limitations of the AAD process are summarized and presented in this work. Difficulties in development of the complex rheological model that takes in to account strain path changes in the deformed material are also presented and discussed.

Tytuł:: Simulation of stress paths derived from FEM analysis in triaxial tests

Opis:: Reliable estimation of geotechnical parameters is often based on reconstruction of a complete loading process of subsoil on a specimen in laboratory tests. Unfortunately laboratory equipment available in many laboratories is sometimes limited to just a triaxial apparatus - the use of which generates difficulties whenever a non-axisymmetric problem is analysed. The author suggests two simple operations that may be done to improve the quality of simulation in triaxial tests. The first one is based on the use of triaxial extension along the segments of the stress path p’-q-θ for which the Lode’s angle values are positive. The second one consists in a modification of the equivalent stress value in such a way that the current stress level in the specimen complies with results of FEM analysis.
