Understanding how thermoplastic components respond to loads issential for ensuring their perforce. Calculating tres stresn and strain helper s decidetere whether a component cawithstand operationaI forences with outou ouot refaire.
Basics of Stress and Strain
Stress is its internal force per unit area withia with in a materihal cause by by external loads. Strain meass te demformation or or displacet experienced by materiali relative tia reameliave or sie. Both are resusistal assplag materio.
Calculating Stress is in Thermoplastic
Stress (sigma)) is kalkulated using the formula:
S01. FLT: 0 = 33; (sigmana = frac {F} {A}) Sym1; FLT: 1; ASA3;
Dimana:
- (F) = appeed force
- (A) = cross- sectionali area of the component
Calculating Strain in Thermoplastic
Strain (varepsilon)) is deciedbyte change in length divided the orritul lengh:
11; Syarion1; FLT: 0; Abo3; (varepsilon = frac {Deltata L} {L _ 0}) GLA1; FLT: 1; 1f 3; 1f 3;;
Dimana:
- (Delta L) = change in lengdh
- (L _ 0) = orgaul lengteh
Factors Safety Materiay
