    Notes: Least squares smoothing is applied to thermal strain calculation. The smoothing procedure eliminates apparent errors in thermal stresses due to mismatch of thermal and mechanical strain orders which facilitates direct evaluation of results. General procedures are developed and demonstrated for two-dimensional isoparametric elements. Examples serve to illustrate the effectiveness of the smoothing procedure.

    Notes: Finite element calculation and the nonlinear temperature-dependence of thermal strain are reviewed using basic principles. An approach for thermal strain calculation based on an instantaneous coefficient of thermal expansion, material description, is presented for incremental finite element analysis. The approach is then related to the current calculation method which uses a reference-dependent mean expansion coefficient. Implications of the alternative approaches are discussed, and the principles are applied to actual expansion data for an epoxy. The paper is written to aid finite element analysts and code developers on thermal strain calculation.
