S24  Mecânica dos Sólidos    Titulo: A STUDY ON THE HARDENING IN A PARTICULAR MODEL FOR PSEUDOELASTIC MATERIALS   Resumo : IN A RECENT PAPER, SOUZA ET AL. PROPOSED A NEW MECHANICAL MODEL FOR PSEUDOELASTIC AND SHAPE MEMORY ALLOYS IN THE SETTING OF THREE DIMENSIONAL MEDIA. QUALITATIVE AGREEMENT WITH EXPERIMENTAL STRESS-STRAIN DATA WAS OBSERVED WHEN CONSIDERING BOTH PROPORTIONAL AND NONPROPORTIONAL LOAD CASES. THE GOAL OF THE PRESENT PAPER IS TO INTRODUCE NEW FEATURES INTO THE AFOREMENTIONED MECHANICAL MODEL IN ORDER TO OBTAIN CLOSER QUANTITATIVE AGREEMENT BETWEEN MODEL AND EXPERIMENTS. IN PARTICULAR, WE DISCUSS IMPROVEMENTS IN THE TERM ASSOCIATED WITH THE HARDENING OF THE MATERIAL, VERY OFTEN OBSERVED DURING STRESS INDUCED PHASE TRANSFORMATION PROCESSES.    Autores : Guillen, Leonardo Lanna Mamiya, Edgar Nobuo Mota, Leonardo Boselli da Vianna, Dianne Magalhaes     Trabalho Completo :   COBEM99 | Comissão  Organizadora | Palestras | Sessões Técnicas | Autor | Simpósios e Sessões Especiais | Revisores |  Título  dos  Trabalhos | Local
