Abstract

Polimerowa belka pomiarowa zawierająca rdzeń (1) z kształtowym koncentratorem naprężeń (2) o cylindrycznych powierzchniach ograniczających oraz układy pomiarowe lub ich elementy, umieszczone w obszarze największych naprężeń i w sposób jednorodny zespolone z materiałem rdzenia belki, przy czym rdzeń belki wykonany jest z polimerowego materiału termoplastycznego lub z polimerowego materiału duroplastycznego: termoutwardzalnego lub chemoutwardzalnego, charakteryzuje się tym, że koncentrator naprężeń w przekroju wzdłużnym belki ma kształt opisany co najmniej jednym okręgiem lub co najmniej jedną krzywą zamkniętą, symetryczną lub asymetryczną względem osi pionowej lub poziomej lokalnego układu współrzędnych koncentratora, której kształt ograniczono dwiema liniami narzucającymi warunek zbieżności w kierunku przeciwnym do pożądanego gradientu przyrostu naprężeń wzdłuż osi belki, przy czym tak ukształtowany koncentrator naprężeń może być usytuowany symetrycznie lub asymetrycznie względem pionowej lub poziomej osi belki.
