A passive isolator mount capable of dissipating shocks and vibrations as either heat or magnetic energy is presented. The passive isolator includes a pair of L-shaped or C-shaped brackets capable of withstanding repeated deflections and strains, energy dissipating layers disposed along each bracket, and a bond layer. The energy dissipating layers are composed of a rare earth element or alloy, a ferromagnetic shape alloy, a magnetic shape memory alloy, a magnetostrictive alloy, a magneto-mechanical alloy, a super-elastic alloy, or a combination thereof. The bond layer is disposed between and adheres one energy dissipating layer along a first bracket to an energy dissipating layer along a second bracket so that the resultant passive isolator is C-shaped. Energy dissipating and bond layers completely bisect the passive isolator either widthwise through the thickness of the L-shaped brackets or lengthwise through the thickness of the C-shaped brackets.
