Hydrogels　are　polymer　materials　with　network　structure　formed　by　the　hydration　of　polymer　chains,　which　have　received　extensive　attention　in　the　fields　of　biomedicine　and　flexible　electronics.　However,　pure　water　gel　materials　have　problems　such　as　low　strength　and　poor　toughness.　The　mechanical　properties　of　hydrogel　materials　can　be　improved　as　a　whole　by　adding　strong　fibers　into　the　hydrogel　matrix　to　form　hydrogel　composites,　so　as　to　enhance　the　practical　value　of　hydrogels.　Although　there　have　been　a　lot　of　research　reports　on　fiber　reinforced　hydrogel　composites,　the　deformation　mechanism　of　hydrogel　composites　has　not　yet　been　clarified;　Compared　to　research　methods　such　as　experiments　and　constitutive　modeling,　numerical　simulation　methods　have　the　advantages　of　being　able　to　better　compensate　for　the　shortcomings　of　both　research　methods;　However,　the　systematic　numerical　study　of　the　deformation　of　continuous　fiber　reinforced　hydrogel　composites　using　the　traditional　finite　element　method　requires　a　huge　computational　cost.　Therefore,　this　paper　selects　a　dual　scale　method　Direct　FE2,　which　can　not　only　better　capture　the　evolution　of　composite　microstructure,　but　also　greatly　improve　the　computational　efficiency,　to　carry　out　systematic　numerical　simulation　on　the　deformation　and　failure　behavior　of　fiber　reinforced　hydrogel　composites　with　different　microstructure　characteristics,　and　discusses　the　influence　of　fiber　microstructure　characteristics　on　the　deformation　and　failure　of　hydrogel　composites　based　on　the　simulation　results.　The　research　results　can　provide　guidance　for　the　design,　manufacturing,　and　engineering　service　reliability　of　FRHC　sensors.　©　2023　IEEE.
