dma fatigue testing instrument

Fatigue testing machines

In numerous industrial applications materials are subjected to cyclic loading that generates failure mechanisms. Fatigue analysis and consequent life prediction are then major issues. The new DMA+ series instruments are dynamic testing machines based on an innovative concept of one-piece high rigidity test frame which offers the largest stiffness and frequency analysis ranges, along with first-class ergonomics.

MULTITEST software makes possible an extended variety of fatigue tests as well for materials specimens as for industrial components. Optional DYNATEST software makes possible to combine in one single testing machine, fatigue testing capabilities with DMA testing capabilities, making DMA+ series instruments unmatched powerful testing platforms.
