Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh perubahan morfologi akibat perendaman dinamis terhadap perilaku mekanis perancah tulang magnesium berpori. Sampel perancah direndam dalam waktu 24, 48, dan 72 jam. Sembilan sampel setelah terdegradasi dilakukan pemindaian dengan alat pemindai microCT dan direkonstruksi menjadi model 3D serta dilanjutkan analisis elemen hingga untuk memperoleh perilaku mekanisnya. Sifat mekanis meliputi modulus elastisitas efektif (Eff) dan tegangan luluh (σ_0.2) daru simulasi elemen hingga didapatkan kemudian dibandingkan dengan hasil eksperimental. Hasilnya menunjukkan bahwa nilai modulus elastisitas efektif dan tegangan luluh mendekati kondisi aktual. Degradasi akibat perendaman dinamis pada sampel perancah Mg berpori secara signifikan mempengaruhi perubahan morfologi sampel. Hubungan antara parameter morfologi meliputi fraksi volume, porositas, dan luas area permukaan sampel terhadap perilaku mekanis telah sepenuhnya diperoleh dalam penelitian ini. Kata kunci: Perancah tulang Mg berpori, perilaku mekanis, simulasi elemen hingga, morfologi
