bone fracture demands the use a bio-degradable implantplate with a lengthof 50mm and a width of 10mm.The healing timecorresponding to full bone reconstruction along with complete implant degradation (100% corrosion) is expected to be 1 year. The materialof choice for the implant is a magnesium alloy having a density of 1.8g/cm3and a corrosion penetration rate of CPR=1mm/year.Note the corrosion constant K=87.6. (a)What should be the implant plate thickness to meetthese requirements?(a)What can be done if the healing time will have to be increased for another 6months?Suggest and justify at least two opportunities.
