Pressure gradient → Cooling

Matrix context

D = disequilibrium row · C = coupling family column. A cell reads the state of the atlas for that pair.

D.02 × C.09 · Pressure gradient × Caloric (magneto/electro/elasto)family: Caloric (magneto/electro/elasto)

Steps

   Pressure gradient —drives→ Elastic deformationestablishedclaim record

   mechanical → mechanical

   • pressure acting on a diaphragm or shell

   Elastic deformation —produces→ Mechanical stress or strainestablishedclaim record

   mechanical → mechanical

   • the deformed member carries a cyclic stress or strain state that can drive a stress-driven conversion (flexoelectric
   • elastocaloric
   • piezoelectric)

   mechanical → thermal

   • stress large enough to drive the martensitic transformation of a shape-memory alloy
