The Poiana Cireşului Upper Paleolithic site is located on the erosion level cut into the flysch strata, roughly equivalent in altitude to the middle (45 m) Bistriţa’s terrace, on the right shore of the river, 4 km N-W from the city of Piatra-Neamţ (North-Eastern Romania). The systematic excavations are currently carried out by an international Romanian, German and French team. The paper focuses on the recent results obtained during the last stage of research (1998– 2005) campaigns. The site displays one Neolithic layer and four documented paleolithic stages of occupation, already systematically uncovered during the last seven years. At least two more archaeological horizons lay below the last excavated one, as shown by the recent drills. The thin Neolithic layer stands in some poorly preserved pottery remains and a few scattered lithic tools, and it apparently belongs to Criş archaeological culture. The Paleolithic human presence is much more consistent. Except the very thin Tardiglaciar Epigravettian layer, partially disturbed by the late Neolithic activity, three other horizons were identified : a rich Epigravettian layer, resulted from at least three occupational episodes (Epigravettian II) and two Gravettian layers (Gravettian I and II). The paper stresses the richness of the archaeological record in the Epigravettian and Gravettian II layer. In this respect, the technological analysis of the stone and bone/ antler/ ivory industry is presented, together with a brief description of the stratigraphical evidences. The excellent state of preservation of the organic material, together with the richly documented human activity and the long geological sequence point to the central importance Poiana Ciresului holds, both for the understanding of the long-term Paleolithic cultural dynamics in this area and for the short-term behavioral variability.
Analiza pieselor, provenite dintr-un sondaj efectuat în anii '80 în aşezarea de tip teii, a fost axată pe studiul tehnologic al pieselor, fapt posibil şi datorita gradului de rragmentaritate al acestora.Au fost identificate patru grupe definite în functie de criterii tehnologice şi morfologice, fiind sesizată o asociere a unui mod de fabricare cu un tip specific de expresivitate plastică şi artistică, corespunzând şi unui tip de fragmentare diferen\iat.Datorită lotului redus de piese nu s-au putut trage concluzii privind existenta unor variaţii tehno-tipologice din perspectivă diacronă, având în vedere faptul că stratigrafic sunt menţionate mai multe etape culturale.Cuvinte cheie: plastică antropomorfă, tehno-tipologic/analiză tipologică şi tehnologică, Morteni, Gumelniţa.

The analysis of damage resulted from concentrated out-of-plane impact forces is a concern in case of fiber reinforced polymeric composite aerostructures. Thereby, it can be quantified in terms of resulting size/damage type by drop weight impact testing. The aim of the present research was to evaluate the impact response of CFRP laminates by FEA and experimental tests. For FEA, two failure criterions were used, energetic criterion and Tsai Wu criterion. In both modeling scenarios the laminate was fractured. In case of the energetic criterion it was observed a meandering crack along with internal delamination of the material plies, while in case of the Tsai Wu criterion the impactor passes through the specimen, destroying the impacted area. Experimental tests performed at 0.7 meters height and 33 J of impact energy showed that all material plies were visible damaged, but the impactor didn’t pass through all specimen thickness. Different damage modes were observed on the tested specimens, the impacted face of the specimen presented a combined damage consisting in large cracks with fiber breakage indentation/puncture and a dent while on the non-impacted side of the specimen splits, cracks and a small swelling were observed. Considering the results from FEA and experimental tests, it can be said that regarding the damage shape, the experimental results are in a good agreement with a combination of the results obtained from the two failure models of FEA.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
