The two major repair configurations for sandwich structures, namely overlap and scarf repair, are studied. The interface elements, placed at the middle of the adhesive, parent laminate\/adhesive and adhesive\/patch interfaces, allow to obtain stress distributions at these locations as well as to simulate damage onset and growth. The influence of several geometrical parameters, such as overlap length and patch thickness for overlap repairs, and scarf angle for scarf repairs, is evaluated in terms of stress analysis and strength predictions. Conclusions were drawn about design guidelines of the sandwich composite repair.\n                  <\/jats:p>","DOI":"10.1177\/1099636209104520","type":"journal-article","created":{"date-parts":[[2009,6,24]],"date-time":"2009-06-24T20:45:07Z","timestamp":1245876307000},"page":"369-390","source":"Crossref","is-referenced-by-count":20,"title":["Stress and Failure Analysis of Repaired Sandwich Composite Beams using a Cohesive Damage Model"],"prefix":"10.1177","volume":"12","author":[{"given":"D.A.","family":"Ramantani","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering and Industrial Management, Faculty of Engineering, University of Porto, R.
