Viscoplasticity Stress-strain response of a viscoplastic material at different strain rates. The dotted lines show the response if the strain-rate is held constant. The blue line shows the response when the strain rate is changed suddenly. Institute of Structural Engineering Method of Finite Elements II 32
NL FE Special Considerations - The Contact Problem Difficult non linear behavior = contact between two or more bodies Contacts = From frictionless in small displacement to friction in general large strain conditions Nonlinearity of the analysis is not only geometric and material but also contact conditions Institute of Structural Engineering Method of Finite Elements II 33
