Tucker, Charles L., III Li, Min 2015-09-25T21:11:59Z 2015-09-25T21:11:59Z 10000-01-01 2001 2001 A finite element method is then developed to solve two-dimensional consolidation problems. The consolidation governing equations, one for solid stress and one for fluid pressure, are derived using a local volume averaging approach, and they are strongly coupled. A special anisotropic hyperelastic constitutive equation is developed for the solid stress, and a full Lagrangian approach is implemented to solve the equations, using implicit time integration and a successive substitution method. The code is applied to explore two-dimensional consolidation effects. A free edge affects the thickness profile during consolidation, but the final thickness can still be uniform. This effect is substantial in the region close to the edge. Simulations were also performed for laminates that bend to form a corner. The corner is thicker than the flat region after consolidation. Wiggles, similar to fiber buckling, arise at low values of shear modulus when using a male mold. Large values of the solid shear modulus cause the corner effect to extend far into the adjacent flat region. The length of the flat region also affects the consolidation of the corner.
