1. 1. Continuum Mechanics Modelling of Corrugated Board

   Författare :Ulf Nyman; Institutionen för byggvetenskaper; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material technology; assumed natural strain shell; failure criterion; lifetime; reliability; moisture transport; sorption hysteresis; corrugated board; hygro-elasticity; Materiallära; materialteknik;

   Sammanfattning : The storage of compressive loaded boxes in an environment with naturally varying humidity is a practical issue in corrugated board employment. Time dependent variables such as moisture content, strain fields, stress fields and material strength play important roles for the time to failure. LÄS MER
