Приводится описание и определение отслоения – предельного состояния, свойственного конструкциям, усиленным внешне ФАП-армированием. Обосновывается актуальность учета отслоения при проектировании. Описан процесс численного моделирования испытания изгибаемого железобетонного элемента, усиленного внешним ФАП ламинатом. Особое внимание уделено заданию контакта фиброармированного полимера с бетоном. Проведено исследование влияния геометрических характеристик ФАП (ширины, толщины и площади поперечного сечения) на межфазные напряжения в фиброармированном полимере и бетоне на их границе раздела.
