Equibiaxial test of elastomers
, 2007 Našim cílem je stanovit nelineární materiálové parametry eleastomerů pro numerickou simulaci těchto materiálů. Pro tento účel je nutné testovat materiál ve třech různách módech zatěžování: jednoosý tah, dvouosý tah a čistý smyk.

Thermoplastic Elastomers [PDF]
, 2015 Thermoplastic elastomers (TPEs), commonly known as thermoplastic rubbers, are a category of copolymers having thermoplastic and elastomeric characteristics. A TPE is a rubbery material with properties very close to those of conventional vulcanized rubber

Design and Synthesis of Peptide‐Polyester Conjugates for Cell‐Mediated Scaffold Degradation
Advanced Healthcare Materials, EarlyView.This work describes polycaprolactone (PCL)‐based biomaterials engineered to degrade in response to cell‐secreted proteases. A fast‐degrading peptide (Fast) sequence is integrated into a PCL conjugate backbone to produce a biomaterial that is selectively degraded by multiple cell types compared to its scrambled control (ScrFast).
