Abstract This paper is based on a ductile failure simulation under dynamic loading conditions using finite element (FE) analyses. proposed to implement fracture the energy numerical model. The model determined be incremental damage in terms of stress triaxiality ( σ m / e ) and strain W f for dimple from tensile test result with FE analyses technique. Since effect especially important assess crack-like defect components, this work propose integrated which combines quasi-static effect. In...
This study aimed to evaluate the differential positional changes of proximal and distal segments during mandibular setback surgery relapse. Thirty patients with prognathism who underwent bilateral sagittal split ramus osteotomy were included. Skull models from pretreatment, postsurgery, post-treatment cone-beam computed tomography superimposed condylar displacement rotational changes, determine center rotation (CRot) in segments. During postsurgical relapse, segment rotated 2.4 ± 2.1°...
This paper investigates effect of thermal aging on reduction fracture toughness CF8 M cast stainless steel. To predict un-aged and aged materials by numerical analyses, finite element damage analysis is used in conjunction with strain-based model. The models for are determined from notched bar tensile test data it. It found that the material ductility can be quantified introducing concept constant. Using method this paper, J-resistance curves predicted compared experimental data.
Abstract This paper presents a procedure to predict fracture toughness of steel material using small punch test (or notched test) and finite element (FE) damage analysis. Tensile property can be determined from setting the constitutive equations validated by comparing (SP) data with FE results applying tensile property. analysis used in this is based on strain-based model. Material constants model are normally analyzing bar tests. To determine these SP instead tests, simplified (with only...
