Choose geometry (cylinder drum and breastplate) and material properties MS and stainless steel(poison ratio, yield strength, density)

Meshing Generation(Mesh size, hight stress/strain)

Check grid ratio and quality

Boundary condition and Load (roller support for cylinder drum) and Fixed support breastplate

Static loads(pressure, force)

Dynamic loads (time-varying forces, impact), feed rate, speed rate)

Static Analysis (displacement, stress, strain Evaluate safety factor)

Modal Analysis (natural frequencies and mode shapes)

Harmonic Analysis Evaluate response loading

Transient Dynamic Analysis (Analyze time-varying loads, impact, etc)

Result post processing

Result post processing

Stress/strain distribution Mode shapes (for vibration analysis) Fatigue analysis

Optimization

Modify design to avoid failure zones (stress, fatigue, resonance) Minimize weight or material usage
