This　paper　experimentally　and　numerically　investigates　the　nonlinear　vibrations　and　dynamic　snap-through　behaviors　of　the　bistable　asymmetric　carbon　fiber-reinforced　[90n/0n]　composite　laminated　shallow　shell.　In　the　experimental　research,　in　order　to　produce　the　dynamic　snap-through　phenomena,　the　center　of　a　bistable　asymmetric　composite　laminated　shallow　shell　is　clamped　on　an　electromechanical　shaker.　The　shaker　provides　the　controlled　frequency　and　amplitude　of　the　foundation　excitation.　A　laser　displacement　testing　system　collects　the　data　of　the　vibration　signals　for　the　bistable　asymmetric　composite　laminated　shallow　shell.　A　high-speed　camera　captures　the　steady-state　vibrations　of　the　bistable　asymmetric　composite　laminated　shallow　shell.　The　experimental　results　demonstrate　the　influence　of　the　structural　parameters　on　the　dynamic　snap-through　phenomena　and　nonlinear　vibrations　of　the　bistable　asymmetric　composite　laminated　shallow　shell.　The　amplitude-frequency　response　curves　are　obtained　by　the　experimental　results.　The　bifurcation　diagrams,　phase　portraits,　time　histories,　power　spectrums,　and　Poincaré　maps　are　obtained　to　experimentally　and　numerically　illustrate　the　single-well　periodic,　chaotic　and　double-well　chaotic　vibrations　of　the　bistable　asymmetric　composite　laminated　shallow　shell　under　the　center　foundation　excitation.　In　numerical　research,　ABAQUS/CAE　is　used　to　simulate　the　dynamic　responses　of　the　bistable　asymmetric　composite　laminated　shallow　shell.　The　subspace　iteration　method　is　utilized　to　give　the　vibration　modal　analysis.　The　vibration　modes　in　the　experimental　research　are　qualitatively　consistent　with　the　results　of　the　ABAQUS　numerical　simulation.　The　phenomenon　of　the　energy　transfer　from　the　high-order　to　low-order　primary　resonance　is　discovered.　The　results　of　the　experiment　and　numerical　simulation　are　well　verified　with　each　other.　©　2021　Elsevier　Masson　SAS
