DESCRIPTION:Prof. Gerald Pinter\, Chair of Materials Science and Testing 
 of Polymers\, Department of Polymer Engineering and Science\, Montanuniver
 sitaet Leoben\, Austria\nPolymers are widely used in civil engineering app
 lications\, either as primary or as secondary structural components. Two e
 xamples are presented in this talk and appropriate design and life assessm
 ent methods are discussed.\n\nThermoplastic Pipes\nFracture mechanics life
 time and safety assessment of thermoplastics pipes is based on the knowled
 ge of material specific creep crack growth (CCG). However\, with common te
 st methods the investigation of this failure mechanism is not possible in 
 modern thermoplastic-pipe materials in a feasible time. For an accelerated
  generation of CCG an extrapolation concept based on fatigue tests with cr
 acked round bar (CRB) specimens was developed and integrated into a lifeti
 me prediction model for pressurized pipes. In that way it is possible to c
 alculate the lifetime of pipe systems under real service conditions in a r
 easonable time.\n\nSolar thermal façades \nUtilizing façades for energy 
 conversion\, distribution\, and storage is a key criterion for increasing 
 the energy efficiency of buildings. In this regard\, the usage of façade-
 integrated solar thermal collectors is highly interesting. However\, high 
 absorber temperatures during collector stagnation often cause a significan
 t heat transfer from the collector to the interior and thus increase the i
 nterior thermal load. Whereas latent heat storage is already well establis
 hed for active and passive cooling and thus for the heat management of bui
 ldings\, recent numerical simulations also revealed their high potential t
 o effectively prevent overheating of buildings with solar thermal façades
 . The proof of concept with appropriate polymeric latent heat storage (PCM
 -polymer compound) as well as a representative solar thermal façade eleme
 nt will be demonstrated.\n \nBio: Prof. Gerald Pinter is Chair of Materia
 ls Science and Testing of Polymers at the Department of Polymer Engineerin
 g and Science at the Montanuniversitaet Leoben\, Austria and Area Manager 
 of the Polymer Competence Center Leoben GmbH\, the leading Austrian Center
  of Excellence for application oriented research in the field of polymeric
  materials. He is board member of the European Structural Integrity Societ
 y (ESIS-Austria)\, Carbon Composite Austria (CC Austria) and the European 
 Society of Composite Materials (ESCM). The research of his group deals wit
 h the “Reliability of plastics and composites in structural applications
 ” and “Sustainable materials and recycling technologies”.
