000015353 520__ $$2eng$$aA finite strain generalization of the thermodynamically consistent strain gradient plasticity (SGP) theory by Gudmundson [1] is proposed. The SGP theory, as originally formulated, employs both dissipative and energetic strain gradient effects, and it is shown that a finite strain generalization is readily developed when ignoring energetic gradient effects. An updated Lagrangian finite element method is formulated, and matters of the finite strain implementation turn out to be mainly those associated with generalizing conventional plasticity theory. The framework developed is applied to ductile void growth on the micron scale. Quantitative predictions show that the growth rate for micron size voids is suppressed compared to that predicted by conventional plasticity.
