Kursus: Forståelse af mekaniske egenskaber ved termoplast

Selvom det ikke er udtømmende, går kurset tilstrækkeligt i dybden med emnet for at etablere en solid vidensbase. Det forbereder deltagerne til specialiseret læsning eller træning inden for deres specifikke interesseområde.

Dette kursus, uanset deltagelse i BIMS-1 (Forståelse af sprøjtestøbning af termoplast), fokuserer på plasts komplekse mekaniske ydeevne og introducerer nøgleadfærd såsom viskoelasticitet, ikke-linearitet, krybning, slagpåvirkning og fejlmekanismer. Det henvender sig til en bred målgruppe, herunder design- eller maskiningeniører, støbere, FEA-specialister, projektledere, forskere, materialespecialister, studerende og erfarne fagfolk.

Fra og med 2024, på grund af kursusets nye placering på DTU, vil Teknologisk Videndeling præsentere en times oplæg af Prof. Guido Tosello eller en af hans medarbejdere. Emnet vil være tæt knyttet til nogle af BIMS-2’s undervisning.

Sammenfattende tilbyder dette kursus en kondenseret, men omfattende udforskning af polymerers mekaniske egenskaber, der fremmer interaktion og netværksmuligheder, hvilket gør det til en uvurderlig oplevelse for professionelle på tværs af forskellige discipliner.

Kurset er på engelsk.

Course content

The teaching material (over 250 slides) provides an in depth introduction in the field of plastic mechanical performance. Upon completion of the course, participants will gain insightful answers to a variety of common questions encountered in the realm of plastics, including:

• Why does the modulus of plastics exhibit significant changes with temperature, and why does this change vary among different polymers?
• Why do amorphous polymers often undergo brittle failure in long-term tests or impact, while some demonstrate resilience in such conditions?
• What constitutes the “brittle-ductile” transition in polymers, and why are some polymers ductile at specific test rates but brittle at lower and higher strain rates? What role does test timing play in plastics?
• How does plastic performance undergo considerable variations with processing conditions, even in unfilled and amorphous states?
• Why do polymers undergo aging, and what implications does this have on their performance?
• What mechanisms underlie rubber reinforcement, and why is the morphology of these blends crucial, necessitating tailored formulations for each specific polymer?
• What is Yielding? What is plastic flow? Why do certain polymers exhibit “shear-banding” and necking in tensile experiments, while others do not?
• What role does crystallinity play in the mechanical properties of plastics?
• Why, at the same temperature, do polymers generally fail at different times and stress levels in short versus long-term (creep) tests? Can long-term performance be predicted from shorter-term tests?
• How can the intrinsic mechanical properties of polymers at large strains be accurately measured without artifacts like necking or premature failure?
• Why do glass fibres enhance modulus and strength but reduce elongation at break? What are the reinforcing mechanisms, and how critical is the interfacial strength between the matrix and filler? What constitues the optimum fibre length?
• Why is it common to test plastics with and without a “notch”? What occurs at the notch, and why do some polymers still perform when notched while others do not?
