Fig. 8 Stress linearization ( MPa ) on stiffener plate of job-carrier.

The computed maximum deformation ( z -direction) in the job-carrier is 0.3 mm, which is considered acceptable under the current loading conditions, as illustrated in Fig. 9(a). This deformation value indicates that the structure can withstand the applied loads without exceeding the acceptable deformation limits.

(a) (b) Fig. 9 (a) Job-carrier deformation ( mm ) in z-direction under loaded condition. (b) Job-carrier expansion ( mm ) in z-direction under loaded condition when temperature of the complete assembly is ramped to 1200 deg C 3.3. Case 2 In this case, the entire assembly's temperature was gradually increased to 1200 deg C while in loaded condition. Surprisingly, even under a load of 400 kg, the thermal expansion exhibited almost complete freedom, as no significant increase in stress was observed in the job-carrier. As a result, for the sake of brevity, stress-based analysis is not included in this context. Similarly, the trend seen in the displacement in the z -direction, as illustrated in Fig. 9 (b), also indicates that the job-carrier experiences nearly unrestricted expansion, unaffected by the applied load. The absence of stress variation despite temperature changes highlights the system's ability to undergo thermal expansion without a notable impact on its mechanical response.
