AB - The impact of materials is undoubtedly the object of research, due to the dynamic
condition inherent in the bodies that interact in our universe. This work places
special emphasis on the method of plate bending, which, due to its geometric
configuration, interprets real impact situations to which some bodies are subjected,
in addition to the low energy technique in which the energy available in the
impactor is less than that absorbed in the breaking process, makes it possible to
obtain information on the material in the elastic, plastic, initiation and crack
propagation range. For research, the contribution of technological progress in
instrumented test equipment by electronics is important, as it allows us to record
much more information on the evolution of the contact between the impactor and
the sample step by step. This information must be further processed and this phase
of the research requires programming, modelling and simulation of the test
dynamics to interpret or even predict the different phenomena that converge in the
fraction of time in which the impact occurs. In this sense, our objective has been to
study the physical behavior of different thermoplastic materials and their response
to impact requests and to develop a series of models that try to simulate the phenomenon, in order to help us establish what happens at each stage of it, this is achieved
using powerful mathematical tools, new contributions from the scientific
community and continuous experimentation achieved in the laboratory. So that
more knowledge can be obtained in this field.
