On modeling shape memory polymers as thermoelastic two-phase composite materials

Temperature and rate dependent thermomechanical modeling of shape memory polymers with physics based phase evolution law

“…These experimental results are frequently used for validation of the models established by other researchers (Chen and Lagoudas, 2008a, b;Gilormini and Diani, 2012;Wang et al, 2009), which have exhibit similar prediction abilities compared with the model by Liu et al Here, we also compare our modeling results with the experimental results carried out by Liu et al (Liu et al, 2006).…”

“…In addition to this dominated thermoviscoelastic approach, in recent years, SMP modeling methods have even incorporated molecular dynamic simulation (Diani and Gall, 2007), quantum mechanics (Zhang et al, 2010), multi-scale modeling (Shojaei and Li, 2013), and statistical mechanics (Shojaei and Li, 2014), etc. Of all these methods, the phase evolution approach, first proposed by Liu et al (Liu et al, 2006) and further developed by other researchers (Baghani et al, 2012;Chen and Lagoudas, 2008a, b;Gilormini and Diani, 2012;Guo et al, 2015;Kafka, 2008;Kazakevic̆iūtė-Makovska et al, 2012;Kim et al, 2010;Long et al, 2010;Pieczyska et al, 2015;Qi et al, 2008;Reese et al, 2010;Scalet et al, 2015;Volk et al, 2011;Wang et al, 2009;Xu and Li, 2010) has become another widely used modeling approach due to its ease of application in design.…”

“…In the work by Gilormini and Diani (Gilormini and Diani, 2012), the recovery behavior was reproduced by simply 'unrolling the history' of the recorded storage strain. In other words, Eq.…”

“…The stress increment 9OE and storage strain development 9• • is coupled together during the programming step and has been derived by Gilormini and Diani (Gilormini and Diani, 2012):…”

Experimental characterization and thermoviscoelastic modeling of strain and stress recoveries of an amorphous polymer network

“…Despite that fact, the number of papers dedicated to modeling shape memory polymers remains limited. We may divide the existing models into two categories: the models based on a bi-phasic representation of the material grounded on the rubbery/glassy state transition, first proposed by Liu et al (2006) and adopted by Chen and Lagoudas (2008), Qi et al (2008), Volk et al (2010), Gilormini and Diani (2012), and the thermoviscoelastic approach early introduced by Tobushi et al (1997) and improved by Diani et al (2006), Nguyen et al (2008), Castro et al (2010), Srivastava et al (2010), Diani et al (2012) and Yu et al (2012).…”
