In　this　paper,　the　dynamic　compression-shear　experiments　on　the　closed-cell　aluminum　foam　with　porosity　of　72%-92%　are　carried　out　by　using　improved　split　Hopkinson　pressure　bar.　A　high　speed　camera　is　used　to　observe　the　dynamic　deformation　behavior　of　the　samples　on　the　compression-shear　loading.　A　finite　element　software　ABAQUS　is　employed　to　simulate　the　dynamic　compression-shear　process　of　closed-cell　aluminum　foam.　The　results　demonstrate　that　there　is　a　compression-shear　band　on　the　samples　during　the　compression-shear　loading.　The　most　severely　damaged　area　of　the　material　is　on　the　compression-shear　band;　Low-porosity　closed-cell　aluminum　foam　has　significant　strain　rate　effect,　however　high-porosity　closed-cell　aluminum　foam　can　ignore　the　strain　rate　effect.　The　yield　stress　of　samples　decreases　with　increasing　samples　angle,　whereas　shear　stress　increase　with　increasing　samples　angle,　and　also　the　corresponding　time　when　the　samples　just　begin　to　yield　decreases　with　increasing　samples　angle.
