This paper investigates a quantitative equivalent modulus using nonlinear finite element analysis (FEA) to reflect coupled factors in affecting the modelling accuracy of two typical distributed- compliance mechanisms. It has been shown that all parameters have influences on the equivalent modulus with different degrees; that the presence of large load-stiffening effect makes the equivalent modulus significantly deviate from the planar assumptions in two ideal scenarios; and that a plate modulus assumption is more reasonable for a very large out-of-plane thickness if the beam length is large.en10.1007/s11465-016-0392-zinfo:eu-repo/semantics/openAccessCoupling FactorsModelling AccuracyCompliant MechanismsEquivalent ModulusFlexure HingesArticle112129134N/AWOS:0003798561000032-s2.0-84970027828Q1
