Abstract:Delaminaatiot ja liimaliitosten murtumiset ovat yleisiä rajapintavaurioita, jotka voivat merkittävästi alentaa rakenteiden kuormankantokykyä. Vaurioiden kriittisyyttä arvioidaan tyypillisesti numeerisilla analyysimenetelmillä, joista kaksi yleisintä ovat virtuaalisen särön sulkemismenetelmä (Virtual Crack Closure Technique, VCCT) ja koheesioelementit (Cohesive Zone Modelling, CZM). Väitöskirjan tavoitteena on tarkastella kyseisten menetelmien rajoituksia ja laajentaa niiden käytettävyyttä. |
